U.S. Precipitation Anomaly

In this NLDAS-2 image of precipitation anomalies, blue = areas of higher precipitation (dark blue = +150mm); yellow/red = areas of less precipitation (dark red = -150mm). Dry conditions evident in March likely increased the wildfire danger in the U.S. Southeast.

NLDAS-2 Data

The North American Land Data Assimilation System Phase 2 (NLDAS-2) is a quality-controlled, and spatially and temporally consistent, land-surface model data set. NLDAS-2 data are available at NASA’s Goddard Earth Sciences Data and Information Services Center (GES DISC).
