and surface temperature and wetness conditions affect and are affected by numerous climatologi-cal, meteorological, ecological, and geophysical phenomena. Therefore, accurate, high-resolution estimates of terrestrial water and energy storages are valuable for predicting climate change, weather, biological and agricultural productivity, and flooding, and for(More)
The USEPA has estimated that over 20,000 water bodies within the United States do not meet water quality standards. One of the regulations in the Clean Water Act of 1972 requires states to monitor the total maximum daily load, or the amount of pollution that can be carried by a water body before it is determined to be "polluted," for any watershed in the(More)
Soil moisture is a critical hydrosphere state variable that often limits the exchanges of water and energy between the atmosphere and land surface, controls the partitioning of rainfall between evaporation and runoff, and impacts vegetation photosynthetic rate and soil microbiologic respiratory activities. Thus, accurate measurements of this variable are(More)
Seasonal agricultural drought monitoring systems, which rely on satellite remote sensing and land surface models (LSMs), are important for disaster risk reduction and famine early warning. These systems require the best available weather inputs, as well as a long-term historical record to contextualize current observations. This article introduces the(More)
