SISTER: Experimental Workflows, Product Generation Environment, and Sample Data, V004
The Space-based Imaging Spectroscopy and Thermal pathfindER (SISTER) activity originated in support of the NASA Earth System Observatory's Surface Biology and Geology (SBG) mission to develop prototype workflows with community algorithms and generate prototype data products envisioned for SBG. SISTER focused on developing a data system that is open, portable, scalable, standards-compliant, and reproducible. This collection contains EXPERIMENTAL workflows and sample data products, including (a) the Common Workflow Language (CWL) process file and a Jupyter Notebook that run the entire SISTER workflow capable of generating experimental sample data products spanning terrestrial ecosystems, inland and coastal aquatic ecosystems, and snow, (b) the archived algorithm steps (as OGC Application Packages) used to generate products at each step of the workflow, (c) a small number of experimental sample data products produced by the workflow which are based on the Airborne Visible/Infrared Imaging Spectrometer-Classic (AVIRIS or AVIRIS-CL) instrument, and (d) instructions for reproducing the sample products included in this dataset. DISCLAIMER: This collection contains experimental workflows, experimental community algorithms, and experimental sample data products to demonstrate the capabilities of an end-to-end processing system. The experimental sample data products provided have not been fully validated and are not intended for scientific use. The community algorithms provided are placeholders which can be replaced by any user's algorithms for their own science and application interests.

GPM GROUND VALIDATION METEOROLOGICAL TOWER ENVIRONMENT CANADA GCPEX V1
The GPM Ground Validation Meteorological Tower Environment Canada GCPEx dataset provides temperature, relative humidity, 10 m winds, pressure and solar radiation data collected by a suite of standard meteorological instruments attached to a 10 m met tower. The GPM Cold-season Precipitation Experiment (GCPEx) addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. Data was gathered over the Ontario region of Canada in 2012 from January 15th through March 1st. Browse images are available online. The observation station was assembled by Automated Transportable Meteorological Observation Station (ATMOS).
The Arabidopsis spaceflight transcriptome: a comparison of whole plants to discrete root hypocotyl and shoot responses to the orbital environment
Arabidopsis thaliana was evaluated for its response to the spaceflight environment in three replicated experiments on the International Space Station. Two approaches were used; GFP reporter genes were used to collect gene expression data in real time within unique GFP imaging hardware and plants were harvested on orbit to RNAlater for subsequent analyses of gene expression with using Affymetrix and SAGE transcriptome analyses. Three tissue types were examined (leaves hypocotyls and roots) and compared to analyses conducted with whole plants. Transcriptome analyses with whole plants suggested that the spaceflight environment had little impact on the transcriptome of arabidopsis however closer examination of selected tissues revealed that there are a number of tissue-specific responses that arabidopsis employs to respond to this novel environment
An environment with strong gravitational and magnetic field alterations synergizes to promote variations in Arabidopsis thaliana callus global transcriptional state
Using diamagnetic levitation we have exposed A. thaliana in vitro callus cultures to five environments with different levels of effective gravity (from levitation i.e. simulated mg* to 2g*) and magnetic fields (10.1 to 16.5 Tesla) and we have compared the results with those of similar experiments done in a Random Position Machine (simulated micro g) and a Large Diameter Centrifuge (2g) free of high magnetic fields. Microarray analysis indicates that there are changes in overall gene expression of the cultured cells exposed to these unusual environments but also that gravitational and magnetic field produce synergic variations in the steady state of the transcriptional profile of A. thaliana. Significant changes in the expression of structural abiotic stress and secondary metabolism genes were observed into the magnet field. These results confirm that the strong magnetic field both at micro g* or 2g* has a significant effect on the expression of these genes but subtle gravitational effects are still observable. These subtle responses to microgravity environments are opposite to the ones observed in a hypergravity one. seven-condition experiment MM2D Arabidopsis culture callus control vs. Treatment (altered gravity simulation GBF). Three GBF were used (LDC (2g) + control RPM (mg) + control and Magnet (mg* 0.1g* 1g* 1.9g* 2g*) + control). Biological replicates: 3 replicates in all conditions and controls except 1.9g* (2 replicates)
GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) RADIOMETER GCPEX V1
The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx dataset contains retrievals of temperature, water vapor, relative humidity, liquid water profiles and surface parameters acquired by a passive microwave radiometer during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada, February 14, 2012 through March 1, 2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow.
Adaptive response of Arabidopsis seedlings in microgravity and Mars reduced gravity environment is enhanced by red light photostimulation
The response of plants to the spaceflight environment and microgravity is still not well understood although there has been an increased emphasis on this topic. Even less is known about plants response to partial or reduced gravity levels. In the absence of the directional cues provided by the gravity vector the plant is especially perceptive to other cues such as light. Here we investigate the response of Arabidopsis thaliana 6-day-old seedlings to microgravity and the Mars partial gravity level during spaceflight as well as the effects of red light photostimulation by determining meristematic cell growth and proliferation. These experiments involve microscopic techniques together with transcriptomic studies. We demonstrate that microgravity and partial gravity trigger differential responses. The microgravity environment activates hormonal routes responsible for proliferation/growth and upregulates plastid/mitochondrial-encoded transcripts even in the dark. In contrast the Mars gravity level inhibits these routes and activates responses to stress factors to restore cell growth parameters only when red photostimulation is provided. This response is accompanied by upregulation of numerous transcription factors such as the environmental acclimation-related WRKY family. In the long term these discoveries can be applied in the design of bioregenerative life support systems and space farming.
GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) PRECIPITATION OCCURRENCE SENSOR SYSTEM (POSS) GCPEX
The GPM Ground Validation Environment Canada (EC) Precipitation Occurrence Sensor System (POSS) GCPEx dataset is comprised of data gathered during the GPM Cold-season Precipitation Experiment (GCPEx), which took place in Ontario, Canada, January 15 - March 1, 2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. The POSS is a bi-static X-band Doppler radar designed by Environment Canada. The POSS measures a signal whose frequency is proportional to the particle Doppler velocity and whose amplitude is proportional to the particle scattering cross-section. Its measurements can be used to provide information regarding precipitation occurrence, type, rate, and raindrop size distribution.
Characterization of Epigenetic Regulation in an Extraterrestrial Environment: The Arabidopsis Spaceflight Methylome [Bisulfite-seq]
When germinated and grown on-board the ISS (International Space Station) plant do not exhibit abnormal structures but they do have altered growth habits and this project aims to investigate the molecular mechanisms that provide the foundation for the altered growth habits observed in orbit. APEX03-2 (Advanced Plant Experiment 03-2) also known as TAGES-ISA (Transgenic Arabidopsis Gene Expression System-Intracellular Signaling Architecture) specifically addresses the growth and molecular changes that occur in Arabidopsis thaliana plants during spaceflight by using molecular and genetic tools and by asking fundamental questions regarding root structure growth and cell wall remodeling may be answered. This investigation advances the fundamental understanding of the molecular biological responses to extraterrestrial environments. This understanding helps to further define the impacts of spaceflight on biological systems to better enable NASA x92s future space exploration goals.
