ECOSTRESS Attitude Daily L1B Global 70m V001

The ECO1BATT Version 1 data product was decommissioned on April 22, 2025. Users are encouraged to use the [ECO_L1B_ATT](https://doi.org/10.5067/ECOSTRESS/ECO_L1B_ATT.002) Version 2 data product.The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission measures the temperature of plants to better understand how much water plants need and how they respond to stress. ECOSTRESS is attached to the International Space Station (ISS) and collects data globally between 52 degrees N and 52 degrees S latitudes. The ECO1BATT Version 1 data product provides both corrected and uncorrected attitude quaternions and spacecraft ephemeris data obtained from the ISS. The data are provided in 1 second intervals by the ISS, and each product file contains vectors from the duration of the orbit. The time elements are copied from the ISS raw data.The ECO1BATT Version 1 data product contains variables of corrected and uncorrected attitude quaternions, spacecraft ephemeris data including Earth-centered inertial (ECI) position and velocity, and associated time elements.Known Issues* Cannot perform spatial query on ECO1BATT in NASA Earthdata Search: ECO1BATT does not contain spatial attributes, so granules cannot be searched by geographic location. Users should search for ECO1BATT data products by orbit number instead.* Data acquisition gap: ECOSTRESS was launched on June 29, 2018, and moved to autonomous science operations on August 20, 2018, following a successful in-orbit checkout period. On September 29, 2018, ECOSTRESS experienced an anomaly with its primary mass storage unit (MSU). ECOSTRESS has a primary and secondary MSU (A and B). On December 5, 2018, the instrument was switched to the secondary MSU and science operations resumed. On March 14, 2019, the secondary MSU experienced a similar anomaly temporarily halting science acquisitions. On May 15, 2019, a new data acquisition approach was implemented and science acquisitions resumed. To optimize the new acquisition approach TIR bands 2, 4 and 5 are being downloaded. The data products are as previously, except the bands not downloaded contain fill values (L1 radiance and L2 emissivity). This approach was implemented from May 15, 2019, through April 28, 2023.* Data acquisition gap: From February 8 to February 16, 2020, an ECOSTRESS instrument issue resulted in a data anomaly that created striping in band 4 (10.5 micron). These data products have been reprocessed and are available for download. No ECOSTRESS data were acquired on February 17, 2020, due to the instrument being in SAFEHOLD. Data acquired following the anomaly have not been affected.* Data acquisition: ECOSTRESS has now successfully returned to 5-band mode after being in 3-band mode since 2019. This feature was successfully enabled following a Data Processing Unit firmware update (version 4.1) to the payload on April 28, 2023. To better balance contiguous science data scene variables, 3-band collection is currently being interleaved with 5-band acquisitions over the orbital day/night periods.

ECOSTRESS Swath Attitude and Ephemeris Instantaneous L1B Global V002

The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission measures the temperature of plants to better understand how much water plants need and how they respond to stress. ECOSTRESS is attached to the International Space Station (ISS) and collects data globally between 52° N and 52° S latitudes. A map of the acquisition coverage can be found in figure 2 on the [ECOSTRESS website](https://ecostress.jpl.nasa.gov/science).The ECOSTRESS Swath Attitude and Ephemeris Instantaneous Level 1B Global (ECO_L1B_ATT) Version 2 data product provides both corrected and uncorrected attitude quaternions and spacecraft ephemeris data obtained from the ISS. The data are provided in 1 second intervals, and each product file contains vectors from the duration of the orbit. The ECO_L1B_ATT Version 2 data product contains layers of attitude and ephemeris data generated by the ISS, which are used to start the geolocation process. These layers also include Earth-centered inertial (ECI) position and velocity, and associated time elements distributed in HDF5 format.Known Issues* Cannot perform spatial query on ECO_L1B_ATT in NASA Earthdata Search: ECO_L1B_ATT does not contain spatial attributes, so granules cannot be searched by geographic location.

The 'FieldOfViewObstruction' metadata field is included in all Version 2 products to indicate possible obstructions: * Before October 24, 2024 (orbits prior to 35724): The field is present but was not populated and does not reliably identify affected scenes. * On or after October 24, 2024 (starting with orbit 35724): The field is populated and generally accurate, except for late December 2024, when a temporary processing error may have caused false positives. * A [list of scenes](https://lpdaac.usgs.gov/documents/2249/obst_all.sort.gz) confirmed to be affected by obstructions is available and is recommended for verifying historical data (before October 24, 2024) and scenes from late December 2024.* The ISS native pointing information is coarse relative to ECOSTRESS pixels, so ECOSTRESS geolocation is improved through image matching with a basemap. Metadata in the L1B_GEO file shows the success of this geolocation improvement, using categorizations "best", "good", "suspect", and "poor". We recommend that users use only "best" and "good" scenes for evaluations where geolocation is important (e.g., comparison to field sites). For some scenes, this metadata is not reflected in the higher-level products (e.g., land surface temperature, evapotranspiration, etc.). While this metadata is always available in the geolocation product, to save users additional download, we have produced a [summary text file](https://lpdaac.usgs.gov/documents/2253/qa_20250423-present.txt) that includes the geolocation quality flags for all scenes from launch to present. At a later date, all higher-level products will reflect the geolocation quality flag correctly (the field name is GeolocationAccuracyQA).

Knowledge and attitudes on infant feeding among Namibian medical students

Understanding the level of knowledge and attitudes of medical students on breastfeeding provides an avenue for interventions that aim at providing them with adequate training on breastfeeding to future health professionals. We aimed to determine the attitudes on infant feeding and knowledge of breastfeeding among themedical students at the University of Namibia, Namibia. We conducted a cross-sectional survey of the medical students at the University of Namibia, Hage Geingob Campus, Namibia. Study participants who consented and from any year of study were included in the study by stratified random sampling based on the year of study. Interviews were administered through a pretested anonymous online questionnaire powered by google forms over 1 month. The questionnaire used contained information on student demographics, an adapted Iowa Infant Feeding Attitude scale to assess attitudes on infant feeding, and items to assess their knowledge on breastfeeding.

Data from: Caregivers' attitude towards people with mental illness and perceived stigma: a cross-sectional study in a tertiary hospital in Nepal

Background: Mental illness is stigmatized in most of the communities and people with such illness are often subjected to defame. Stigma impairs an individual's and their caregiver's physical, social and emotional wellbeing, and health-seeking behavior. Sufficient literature on how often the caregivers of people with mental illness from low and middle-income countries are stigmatized and how they perceive people with mental illness is unavailable. In this study, we examined caregivers' attitude towards people with mental illness and perceived stigma. Methods: We conducted face-to-face interviews with 170 caregivers in an outpatient clinic of a hospital in Nepal using a structured questionnaire. We calculated median and inter-quartile range of the attitude and perceived stigma scores. To assess the correlates, Kruskal Wallis H test and Mann Whitney U test were carried out. Results: Overall median score for the domains: attitude (score range: 18–90) and perceived stigma (score range: 12–60) were 42 and 28 respectively, inter-quartile range being 8 each. Attitude score differed significantly by the sex of caregiver (p<0.05), educational status of caregiver (p<0.001), sex of patient (p<0.05) and type of mental illness (p<0.05). Perceived stigma score varied significantly by caregiver's sex (p<0.05), marital status (p<0.001), educational status (p<0.001), occupation (p<0.05), relation with the patient (p<0.005) and use of alternative treatment modalities (p<0.05). Conclusion: Sex of participant, educational status, sex of patient and type of mental illness were the correlates of attitude towards mental illness. Similarly, sex of participant, marital status, educational status, occupation, caregiver's relation with patient and use of alternative treatment modalities were correlates of perceived stigma. Findings of this study suggest that interventions targeting these high-risk populations might be beneficial to help build a positive attitude and overcome the perceived social stigma.

Data from: Attitudes among transplant professionals regarding shifting paradigms in eligibility criteria for live kidney donation

Background The transplant community increasingly accepts extended criteria live kidney donors, however, great (geographical) differences are present in policies regarding the acceptance of these donors, and guidelines do not offer clarity. The aim of this survey was to reveal these differences and to get an insight in both centre policies as well as personal beliefs of transplant professionals. Methods An online survey was sent to 1128 ESOT-members. Questions were included about several extended donor criteria; overweight/obesity, older age, vascular multiplicity, minors as donors and comorbidities; hypertension, impaired fasting glucose, kidney stones, malignancies and renal cysts. Comparisons were made between transplant centres of three regions in Europe and between Europe and other countries worldwide. Results 331 questionnaires were completed by professionals from 55 countries. Significant differences exist between regions in Europe in acceptance of donors with several extended criteria. Median refusal rate for potential live donors is 15%. Furthermore, differences are seen regarding pre-operative work-up, both in specialists who perform screening as in preoperative imaging. Conclusions Remarkably, 23.4% of transplant professionals sometimes deviate from their centre policy, resulting in more or less comparable personal beliefs regarding extended criteria. Variety is seen, proving the need for a standardized approach in selection, preferably evidence based.

Data from: Effects of a systematically offered social and preventive medicine consultation on training and health attitudes of young people not in employment, education or training (NEETs): an interventional study in France

Background NEETs (young people not in employment, education or training) are at higher risk for poorer mental and physical health. In France, the Missions locales (MLs) are the only social structures dedicated to this population. We sought to determine whether the systematic offer of a social and preventive medicine consultation at a ML might increase NEET participants' access to training in the 12 months following the intervention. Methods This intervention research was a parallel randomised controlled interventional study conducted at five MLs in mainland France in 2011-2012. It included 976 NEETs aged 18 to 25 years who attended one of the five MLs. At inclusion, participants were randomly assigned (1:1:1) to three groups: those in the first group were invited to see a social worker (not studied in this paper), those in the second group were invited to see a doctor and a social worker (intervention group), and the third was a control group. The primary outcome was participation in at least one training session during the year following study inclusion. Results Among the 976 participants, 504 were randomly assigned to the intervention group and 472 to the control group; 704 (72.1%) were included in the analyses. A significantly higher proportion of the participants in the intervention group participated in a training session in the 12 months following the intervention than of those in the control group (63.3% vs 55.6%; p=0.04). This difference was significantly greater for women, those less than 21 years of age, those unstably housed and those with a lower level of education. Conclusions Social and preventive medicine consultations that are fully integrated into the social services for NEETs have an impact on their access to training and contribute to changing some of their health-related behaviours. This may improve their access to the labour market.
