Water Resources

Maps of global soil moisture were created using data from the radiometer instrument on NASA's SMAP Observatory

Water resource management in-person and online trainings focus on accessing, interpreting, and applying remote sensing and model-based hydrologic cycle components and water quality parameters. These include:

  • rainfall
  • snow cover
  • soil moisture 
  • runoff
  • evapotranspiration
  • ground water
  • lake level heights
  • cloud and atmospheric humidity at regional and global scales
  • chlorophyll-a concentration
  • colored dissolved organic matter index
  • euphotic depth
  • water temperature
  • coastal oceans, inland lakes, and estuaries.

Trainings cover these topics and the available NASA data, products and tools for water resources and disaster management. 

Courses are appropriate for policy makers, regulatory agencies, NGOs and other applied science professionals.

+ How do I access Soil Moisture Active Passive (SMAP) mission data?

SMAP data and data products are distributed by two different NASA Distributed Active Archive Centers (DAACs): the Alaska Satellite Facility (ASF) and National Snow and Ice Data Center (NSIDC)

SMAP radar data is only distributed by ASF and can be accessed here (registration is required for download). SMAP radar data can be analyzed using MapReady. Note: there is only 2.5 months of collected radar data. 

All other SMAP datasets (radiometer data) and data products (soil moisture) are distributed by NSIDC.  A number of tools work with SMAP data, including ones included in ARSET trainings:
