MEaSUREs

NASA MEaSUREs Products Overview

The LP DAAC works with the following NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) projects to facilitate the introduction of long-term, consistent, high-quality data records to the land remote sensing community. The following list includes the approved data products which are currently available or are under development for the LP DAAC MEaSUREs collections.  

The MEaSUREs Program enables NASA to expand its understanding of Earth systems through the use of satellite measurements. For more information on the MEaSUREs collections, proposal listings, and what years the proposals were accepted, please click here.

 

Products Currently Available

Shuttle Radar Topography Mission (SRTM)

NASA SRTM V3.0 (SRTM Plus)

Principal Investigator: Michael Kobrick, Jet Propulsion Laboratory

The SRTM collections comprise different postings globally from 60°N to 56°S of rasterized SRTM data with voids filled primarily from ASTER GDEM2, and secondarily from the USGS Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010), or the USGS National Elevation Dataset (NED).  Depending on the location, these data are available in 1 arc-second, 3 arc-second, or 30 arc-second.

Available through Data Pool, GDEx, and USGS EarthExplorer.

 

Vegetation Index and Phenology (VIP)

Principal Investigator: Kamel Didan, University of Arizona

The VIP collections comprise 34 years of a consistent global record of sensor-independent Earth System Data Records (ESDR) of vegetation indices and landscape phenology. The VIP collections are based on MODIS, AVHRR, and Satellite Pour l'Observation de la Terre (SPOT) data inputs.

Available through Data Pool, and NASA Earthdata Search.

 

Web-Enabled Landsat Data (WELD)

Principal Investigator: David Roy, South Dakota State University

The Web-Enabled Landsat Data (WELD) collections include 30-meter composites of Landsat 7 Enhanced Thematic Mapper Plus (ETM+) terrain-corrected (Level 1T) mosaics at weekly, monthly, seasonal, and annual periods for the conterminous United States (CONUS) and Alaska.

Available through Data Pool and USGS EarthExplorer.

 

Global Food Security Support Analysis Data (GFSAD)

Principal Investigator: Prasad Thenkabail, USGS

The GFSAD 1 kilometer collection contains crop density and crop mask classifications for the nominal year 2010 at 1 km resolution. The GFSAD 30 meter collection contains crop extent at 30 m resolution.

Available through Data Pool and NASA Earthdata Search.

 

Global Forest Cover Change (GFCC)

Principal Investigator: John Townshend, University of Maryland

The Global Forest Cover Change (GFCC) collection comprise a global record representing forest change detection at 30 meter spatial resolution. The product suite was derived from enhanced Landsat Global Land Survey (GLS) datasets and includes Surface Reflectance, Tree Cover, Water Cover, and Forest Cover Change data.

Available through DAAC2Disk, Data Pool, and NASA Earthdata Search.

 

Land Surface Temperature & Emissivity (LSTE)

Combined ASTER and MODIS Emissivity database over Land (CAMEL)

Principal Investigator: Simon Hook, JPL

The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Combined ASTER and MODIS Emissivity database over Land (CAMEL) dataset provides monthly emissivity at 0.05 degree (~5 kilometer) resolution.  CAMEL data was created by combining the University of Wisconsin-Madison MODIS Baseline Fit database (UWBF) and the ASTER Global Emissivity Dataset (GED).  The two databases have been integrated to capitalize on the unique strengths of each product's characteristics.

Available through DAAC2DiskData Pool, and NASA Earthdata Search.

 

Vegetation Continuous Fields (VCF)

Principal Investigator: Matthew Hansen, University of Maryland

The VCF collection provides global vegetation continuous fields from Advanced Very High Resolution Radiometer (AVHRR) long-term data records version 4 (LTDR v4) from 1982 through 2016. Version 1 of this data product includes a time series of VCF data at 5600 m resolution containing information on percent of tree cover, non-tree vegetation, and bare ground. Future versions will include tree cover data subdivided into needle leaf, broadleaf, deciduous and evergreen classes. Additionally, future versions will also contain error estimates and quality flags for each data product pixel and for the product as a whole.

Available through DAAC2DiskData Pool, and NASA Earthdata Search.

 
 

Products in Development/Future Products

Global Food Security Analysis & Support Data (GFSAD) 250 meter and 30 meter

Principal Investigator: Prasad Thenkabail, USGS

The GFSAD collection will contain global cropland information, differentiating between rain fed and irrigated cropland areas, for multi-year epochs at 250 meter and 30 meter resolutions. Additionally, information about crop type and cropping intensity will be provided.

 

Global Web-Enabled Landsat Data (WELD)

Principal Investigator: David Roy, South Dakota State University

Global WELD expands WELD processing to the global scale to provide composited, mosaicked, and terrain-corrected (Level 1T) 30-meter Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data for all non-Antarctic terrestrial areas. The existing CONUS and Alaska NASA WELD Earth Science Data Record will be extended back to 1982 in this data collection. The collection also provides a global and CONUS percent land cover product and a land cover change product for the period of 1985 to 2010.

 

Land Surface Temperature & Emissivity (LSTE)

Principal Investigator: Simon Hook, Jet Propulsion Laboratory

LSTE products will be generated from data acquired by sensors in low Earth orbit (LEO) and by sensors in geostationary Earth orbit (GEO). NASA’s LSTE data collection merges different LSTE data from the LEO and GEO observations to develop a set of unified LSTE Earth System Data Records (ESDR) that address the known discrepancies and inconsistencies that can arise, including a complete set of uncertainty statistics valid across multiple missions. LSTE data can be used for a wide variety of applications, from calculating the evapotranspiration of plant canopies to retrieving atmospheric water vapor.

 

NASA Digital Elevation Model (NASADEM)

Principal Investigator: Sean Buckley, Jet Propulsion Laboratory

NASADEM will be a global digital elevation model (DEM) product produced at the full resolution of the Shuttle Radar Topography Mission (SRTM), (e.g., 1 arc-second). 

Available through LP DAAC Provisional Data.
