Ag Blog Update 15 Mar

 

From December to March, Eric Hunt of Atmospheric and Environmental Research, Inc. will be providing weekly maps of the soil moisture index (SMI) from the Noah-MP land surface model in the NASA LIS framework for the entire U.S., South America, and western Russia/Ukraine.

This blog post was partially supported by NASA grant 80NSSC19K1266.

Order of Maps in today’s Ag Blog

  • Figure 3. Western Russia/Ukraine Soil Moisture Index map

Figure 1. Soil moisture index (SMI) map) for the 7-day period ending 11 March 2021. Results are based on output from the 0-1 m (surface to 3.23 feet) layers in the Noah-Multiparameterization (Noah-MP) land surface model. Noah-MP is run in the NASA Land Information System (LIS) framework with the North American Land Data Assimilation Version 2 (NLDAS-2) forcing dataset. The SMI calculation is based on the soil moisture index created in Hunt et al. (2009) such that ‘5’(dark blue) is the wettest and ‘-5’ (dark red) the driest for the period of record.  The period of record used calculate the SMI for the current map is 1979-present.
