Weekly Global Precipitation Accumulation - July 28, 2015

This 7-day accumulated global rainfall data for July 28, 2015 is from the joint NASA/Japan Aerospace Exploration Agency (JAXA) Global Precipitation Measurement (GPM) Mission. NASA precipitation data, to include both Tropical Rainfall Measurement Mission (TRMM) and GPM data, are available through the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC).

Learn more about NASA’s precipitation missions. Learn how to discover and access both TRMM and GPM data.

Effects of Climate Change on Global Food Production

This map shows the Projected Maize Yield Change in % from 1970-2000 Baseline to 2050 using the SRES A1F Scenario. The Effects of Climate Change on Global Food Production from SRES Emissions and Socioeconomic Scenarios dataset is an update to a major crop modeling study by the NASA Goddard Institute for Space Studies (GISS). The crop yield estimates incorporate some major improvements: 1) consistent crop simulation methodology and climate change scenarios; 2) weighting of model site results by contribution to regional and national, and rainfed and irrigated production; 3) quantitative foundation for estimation of physiological carbon dioxide (CO2) effects on crop yields; 4) Adaptation is explicitly considered; and 5) results are reported by country rather than by Basic Linked System region. Learn more about this data product, the inputs and the methodology.

Spring Greenup - North America

This Moderate Resolution Imaging Spectroradiometer (MODIS)/Aqua Normalized Difference Vegetation Index (NDVI) image shows monthly vegetation indices for April 2015 in North America. MODIS NDVI data are available through the NASA Land Processes DAAC (LP DAAC). You can easily subset these data using the MODIS Global Subsetting Tool available through the NASA Oak Ridge National Laboratory DAAC. Reproject, visualize and subset MODIS data using the MRTWeb available through the LP DAAC.

Global FLUXNET Sites

FLUXNET is a global network of micrometeorological tower sites that use eddy covariance methods to measure the exchanges of CO2, water vapor, and energy between terrestrial ecosystems and the atmosphere. More than 500 tower sites from about 30 regional networks across five continents are currently operating on a long-term basis. The overarching goal of FLUXNET is to provide information for validating remote sensing products for net primary productivity (npp), evaporation, and energy absorption. Learn more about FLUXNET and data access.

Soil Moisture Active Passive Mission (SMAP) Brightness Temperature Data

This Soil Moisture Active Passive (SMAP) radiometer data image from March 31 - April 3, 2015 maps surface microwave emissions as brightness temperatures in Kelvin, with strong emissions in reds and weaker emissions in blues. Vegetated rainforests and dry deserts show strong emissions; Greenland and Antarctica have weak emissions. Read the full story for this image. The beta version of Level-1 radiometer data from NASA’s SMAP mission is now available at the NASA National Snow and Ice Data Center (NSIDC) Distributed Active Archive Center (DAAC). In addition, the beta version of Level-1 radar data is now available at the NASA Alaska Satellite Facility (ASF DAAC). SMAP combines coincident L-band radar and radiometer measurements to produce global, high-resolution soil moisture estimates. Learn more about SMAP.

Leaf Area Index for Northern Madagascar

This NASA Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index (LAI) image, acquires on November 1, 2014 shows the structural property of plant canopy on the northern tip of Madagascar, namely the one-sided leaf area per unit ground area. LAI data can be used to calculate environmental variables such as surface photosynthesis, evapotranspiration, and net primary production. MODIS LAI is available from the NASA LP DAAC. LAI data can easily be subsetted and visualized using the NASA ORNL DAAC MODIS Global Subsetting Tool and the MODIS Reprojection Tool (MRT) Web Client at the NASA LP DAAC.

Burn Scar from Waldo Canyon Fire - Summer 2012

In this image, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft on July 4, 2012, healthy vegetation is red, water is dark blue, streets and buildings are gray, and the burned areas are black. The image covers an area of 9.3 by 12.1 miles (15 by 18 kilometers). ASTER data is distributed by the NASA LP DAAC.

Groundwater Storage Trends

About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, according to two new studies led by the University of California, Irvine (UCI). Using data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellite, this GRACE twin satellite image shows groundwater storage trends for Earth's 37 largest aquifers. Of these, 21 have exceeded sustainability tipping points and are being depleted, with 13 considered significantly distressed, threatening regional water security and resilience. This UCI-led study used NASA GRACE data from 2003 - 2013. GRACE data are distributed at the NASA Physical Oceanography DAAC (PO.DAAC).
