For enhanced land-surface initialization, the NASA Land Information System (LIS) is run over Eastern Africa at ~3-km resolution, providing real-time land surface initialization data in place of interpolated global model soil moisture and temperature data available at much coarser resolutions. A 10+ year LIS soil moisture climatology run has been made and will provide the basis for computing soil moisture percentiles to support drought and climate outlooks. Additionally, real-time green vegetation fraction data from the Suomi-NPP VIIRS instrument is being incorporated into the KMS-WRF runs, using the product generated by NOAA/NESDIS. Model verification capabilities are also being transitioned to KMS using NCAR's Model Evaluation Tools (MET) software in conjunction with a SPoRT-developed scripting package, in order to quantify and compare errors in simulated temperature, moisture and precipitation in the experimental WRF model simulations. Future enhancements shall include the assimilation of NASA Soil Moisture Active Passive (SMAP) retrievals into the Eastern Africa LIS simulations and incorporation of GPM/IMERG quantitative precipitation estimates to drive the LIS simulations and verify WRF model precipitation forecasts. This presentation will describe the collaboration between KMS, SERVIR, and SPoRT, discuss the transition and capacity development activities to date, and present selected model sensitivities using the enhanced land surface modeling datasets and verification capabilities.
