MODIS/Aqua Gross Primary Productivity Gap-Filled 8-Day L4 Global 500m SIN Grid V006
The MYD17A2HGF Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MYD17A2HGF Version 6.1](https://doi.org/10.5067/MODIS/MYD17A2HGF.061) data product.The MYD17A2HGF Version 6 Gross Primary Productivity (GPP) Gap-Filled product is a cumulative 8-day composite of values with 500 meter (m) pixel size based on the radiation use efficiency concept that can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. The data product includes information about GPP and Net Photosynthesis (PSN). The PSN band values are the GPP less the Maintenance Respiration (MR). The data product also contains a PSN Quality Control (QC) layer. The quality layer contains quality information for both the GPP and the PSN.The MYD17A2HGF will be generated at the end of each year when the entire yearly 8-day [MYD15A2H](https://doi.org/10.5067/modis/myd15a2h.006) is available. Hence, the gap-filled MYD17A2HGF is the improved MYD17, which has cleaned the poor-quality inputs from 8-day Leaf Area Index and Fraction of Photosynthetically Active Radiation (LAI/FPAR) based on the Quality Control (QC) label for every pixel. If any LAI/FPAR pixel did not meet the quality screening criteria, its value is determined through linear interpolation. However, users cannot get MYD17A2HGF in near-real time because it will be generated only at the end of a given year.Known Issues* Operational and uncertainty issues are provided under Section 2 in the User Guide. * For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=Aqua&as=6).Improvements/Changes from Previous Versions* The product uses updated Biome Property Look-Up Tables (BPLUT) and an updated version of the daily Global Modeling and Assimilation Office (GMAO) meteorological data.* The products are now generated at the native resolution of 500 m using the Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index (LAI)/Fraction of Photosynthetically Active Radiation (FPAR) ([MYD15A2H](https://doi.org/10.5067/modis/myd15a2h.006)) 8-day composite at 500 m resolution.
Global MODIS and FLUXNET-derived Daily Gross Primary Production, V2
This dataset provides global gridded daily estimates of gross primary production (GPP) and uncertainties at 0.05-degree resolution for the period 2000-03-01 to the recent past. The GPP was derived from the MODerate-resolution Imaging Spectroradiometer (MODIS) instruments on the NASA Terra and Aqua satellites using the MCD43C4v006 Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectances (NBAR) product as input to neural networks that were used to globally upscale GPP estimated from selected FLUXNET 2015 eddy covariance tower sites. Additional data will be added periodically.
VIIRS/JPSS1 Gross and Net Primary Production Gap-Filled Yearly L4 Global 500m SIN Grid V002
The NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) Gross and Net Primary Production (NPP) Gap-Filled (VJ117A3GF) Version 2 data product is a cumulative composite of Gross Primary Productivity (GPP) values based on the radiation-use efficiency concept that is potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. VJ117A3GF is a yearly composite at 500 meter spatial resolution delivered as a gridded Level 4 (L4) product in Sinusoidal projection.The VJ117A3GF will be generated at the end of each year when the entire yearly 8-day VJ115A2H is available. Hence, the gap-filled VJ117A3GF is the improved VJ117A2, which has cleaned the poor-quality inputs from 8-day Leaf Area Index and Fraction of Photosynthetically Active Radiation (LAI/FPAR) based on the Quality Control (QC) label for every pixel. If any LAI/FPAR pixel did not meet the quality screening criteria, its value is determined through linear interpolation. However, users cannot get VJ117A3GF in near-real time because it will be generated only at the end of a given year. Provided in the VJ117A3GF product are layers for GPP, NPP, along with a quality control layer. A low resolution browse image for GPP is also available for each VJ117A3GF granule.Known Issues* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=VIIRS).

Data from: Nitrogen controls the net primary production of an alpine Kobresia meadow in the northern Qinghai-Tibet Plateau
Net primary production (NPP) is a fundamental property of natural ecosystems. Understanding the temporal variations of NPP could provide new insights into the responses of communities to environmental factors, whilst also contributing to a better assessment of regional carbon storage. However, few studies based on long-term field biomass measurements have directly addressed this subject in the unique environment of the Qinghai-Tibet plateau (QTP). we examined the interannual variations of NPP during 2008-2015 by monitoring both aboveground net primary productivity (ANPP) and belowground net primary productivity (BNPP), and identified their relationships with environmental factors by adopted the general linear model (GLM)and structural equation model (SEM). In addition, the interannual variation of root turnover and its controls were also investigated. The results show that the ANPP and BNPP increased by rates of 15.01 g/m2 and 143.09 g/m2 per year during 2008-2015, respectively. BNPP was mainly affected by growing season air temperature (GST) and growing season precipitation (GSP) rather than mean annual air temperature (MAT) or mean annual precipitation (MAP), while ANPP was only controlled by GST. In addition, available nitrogen (AN) was significant positively associated with BNPP and ANPP. Root turnover rate averaged 30% /yr, increased with soil depth, and was largely controlled by GST. Our results suggest that alpine Kobresia meadow was an N-limited ecosystem, the NPP on the QTP might increase further in the future in the context of global warming and nitrogen deposition.
HOT Primary Production and Flow Cytometry v2022
<p>This dataset consists of measurements of photosynthetic primary production, chlorophyll a and phaeopigment concentrations, and flow cytometry-based determinations of the abundances of heterotrophic bacteria and the picophytoplankton - Prochlorococcus, Synechococcus and small eukaryotic phytoplankton. All samples were collected through the Hawaii Ocean Time-series (HOT) program, which began in 1988 with ~monthly cruises to Station ALOHA (A Long-term Oligotrophic Habitat Assessment; 22° 10 N, 158° 00 W). Photosynthetic production of organic matter was measured by the 14C tracer method. Details on the methods employed over the years are detailed in Karl et al., Progress in Oceanography (https://doi.org/10.1016/j.pocean.2021.102563). Flow cytometry-based determinations of microbial abundances were made using an EPICS 753 flow cytometer on HOT 22-173 (December 1980 – September 2005) and a B/D Influx flow cytometer beginning with HOT 174 . Details on the flow cytometry methods are provided at (https://hahana.soest.hawaii.edu/hot/methods/bact.html). Samples for chlorophyll a and phaeopigments were collected onto Whatman GF/F filters and extracted with 100% acetone and measured on a Turner Designs Model 10-AU fluorometer based on standard techniques described in Strickland and Parsons, 1972. Method details available at (https://hahana.soest.hawaii.edu/hot/methods/chl.html). Time is in a separate column from date. Dates and times are in local time (HST).</p>

HANPP Collection: Global Patterns in Human Appropriation of Net Primary Productivity (HANPP)
The HANPP Collection: Global Patterns in Human Appropriation of Net Primary Productivity (HANPP) represents a digital map of human appropriation of net primary productivity measured in Units of elemental carbon on a one-quarter degree global grid. Net primary productivity (NPP), the net amount of solar energy converted to plant organic matter through photosynthesis, can be measured in Units of elemental carbon and represents the primary food energy source for the world's ecosystems. Humans appropriate net primary productivity through the consumption of food, paper, wood and fiber, which alters the composition of the atmosphere, levels of biodiversity, energy flows within food webs and the provision of important ecosystem services. The data set is distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
HANPP Collection: Human Appropriation of Net Primary Productivity (HANPP) by Country and Product
The HANPP Collection: Human Appropriation of Net Primary Productivity (HANPP) by Country and Product contains tabular data on carbon-equivalents of consumption by country and by type of product. The data were compiled from national-level FAO statistics on consumption of products such as vegetables, meat, paper, and wood. HANPP represents the amount of carbon required to derive food and fibre products consumed by humans including organic matter that is lost during harvesting and processing. Net primary productivity (NPP), the net amount of solar energy converted to plant organic matter through photosynthesis, can be measured in Units of elemental carbon and represents the primary food energy source for the world's ecosystems. These tabular data were used to allocate country level NPP consumption to a spatial surface of NPP consumption (Global Patterns in Human Appropriation of Net Primary Productivity), which is part of this collection.
