Projects > MEaSUREs 1. Overview
Making Earth Science Data Records for Use in Research Environments (MEaSUREs)
NASA, through its Earth Science Data Systems, supports the NASA Earth Science research community in providing Earth science data products and services driven by NASA's Earth Science goals. NASA's Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet in order to inform economic and policy decisions and improve operational services of benefit to the Nation. Through the MEaSUREs Program, NASA is continuing its commitment to expand understanding the Earth system using consistent records. NASA has begun to deploy new types of sensors to provide three-dimensional profiles of Earth's atmosphere and surface. Emphasis is placed into linking together multiple satellites into a constellation, developing the means of utilizing a multitude of data sources to form coherent time series, and facilitating the use of extensive data in the development of comprehensive Earth system models.
2. Overall goal of MEaSUREs
To develop long term, consistent Earth System Data Records (ESDRs) for terrestrial water cycle states and variables by updating and extending previously funded Pathfinder data set activities to the investigators, and by making available the data set to the scientific community and data users via a state-of-the-art internet web-portal.
2.1 MEaSUREs contents
- surface meteorology (precipitation, air temperature, humidity and wind)
- surface downward radiation (solar and longwave)
- derived and/or assimilated fluxes and storages such as surface soil moisture storage, total basin water storage, snow water equivalent, storage in large lakes, reservoirs, and wetlands, evapotranspiration, and surface runoff.
2.2 The specific objectives of the project
- To produce a terrestrial water cycle data set from 1950 to present
- To extend the Pathfinder data set to include two key variables that reflect anthropogenic manipulation of the land surface water cycle
- To merge the above land surface forcings, state variables, and fluxes into a consistent ESDR in a manner that results in closure of the land surface water budget.

3. Accomplishment
MEaSUREs GrADS (The Grid Analysis and Display System) Data Server was developed and deployed at http://unidata.cos.gmu.edu:9090/dods
Also, a data portal for MEaSUREs project was initially developed and deployed at http://grid1.cos.gmu.edu:8080. It is being completed along with this project implementation.
