FLDAS: Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System (NASA/FLDAS/NOAH01/C/GL/M/V001)
Version V001
The FLDAS dataset (McNally et al. 2017), was designed to assist with food
security assessments in data-sparse, developing country settings. It
includes information on many climate-related variables including moisture
content, humidity, evapotranspiration, average soil temperature, total
precipitation rate, etc.
There are multiple different FLDAS datasets; this one uses Noah version
3.6.1 surface model with CHIRPS-6 hourly rainfall that has been
downscaled using the NASA Land Surface Data Toolkit.
which is part of the [Land Information System
framework](LIS; http://lis.gsfc.nasa.gov/). Temporal desegregation is required so that daily
rainfall inputs can be used in both energy and water balance calculations
For forcing data, this simulation uses a combination of the new version of Modern-Era
Retrospective analysis for Research and Applications version 2 (MERRA-2) data and Climate
Hazards Group InfraRed Precipitation with Station data (CHIRPS), a quasi-global rainfall
dataset designed for seasonal drought monitoring and trend analysis (Funk et al., 2015).
