TLDR
The Variable Infiltration Capacity model, a novel blending procedure incorporating the spatial correlation structure of CCD-estimates to assign interpolation weights, is presented and it is shown that CHIRPS can support effective hydrologic forecasts and trend analyses in southeastern Ethiopia.Abstract:
The Climate Hazards group Infrared Precipitation with Stations (CHIRPS) dataset builds on previous approaches to ‘smart’ interpolation techniques and high resolution, long period of record precipitation estimates based on infrared Cold Cloud Duration (CCD) observations. The algorithm i) is built around a 0.05° climatology that incorporates satellite information to represent sparsely gauged locations, ii) incorporates daily, pentadal, and monthly 1981-present 0.05° CCD-based precipitation estimates, iii) blends station data to produce a preliminary information product with a latency of about 2 days and a final product with an average latency of about 3 weeks, and iv) uses a novel blending procedure incorporating the spatial correlation structure of CCD-estimates to assign interpolation weights. We present the CHIRPS algorithm, global and regional validation results, and show how CHIRPS can be used to quantify the hydrologic impacts of decreasing precipitation and rising air temperatures in the Greater Horn of Africa. Using the Variable Infiltration Capacity model, we show that CHIRPS can support effective hydrologic forecasts and trend analyses in southeastern Ethiopia.read more

A Scalable Machine Learning System for Pre-Season Agriculture Yield Forecast
TL;DR: In this paper, a system that incorporates satellite-derived precipitation and soil properties datasets, seasonal climate forecasting data from physical models and other sources to produce a pre-season prediction of soybean/maize yield with no need of NDVI data is presented.

TL;DR: In this article, the authors show that Lassa fever occurrence and incidence is influenced by climate, poverty, agriculture and urbanisation factors, and that heterogeneous reporting processes and diagnostic laboratory access also appear to be important drivers of the patchy distribution of observed disease incidence.

TL;DR: In this article, the authors investigate the relationship between SST and rainfall anomalies using a complex network approach and identify four ocean regions which exhibit the strongest overall SST correlations with central Amazon rainfall, including two particularly prominent regions in the northern and southern tropical Atlantic.

Integration and Evaluation of Forecast-Informed Multiobjective Reservoir Operations
TL;DR: This work has shown that directly incorporating streamflow forecasts into reservoir operations can improve water resources management efficiency, yet the forecast value in multipurpose reservoir systems is rarely investigated.

Characterizing agricultural drought in the Karamoja subregion of Uganda with meteorological and satellite-based indices
TL;DR: In this article, the authors investigated the suitability of NDVI-based drought monitoring in Karamoja and found that in comparison with the existing data, NDVI data currently provides the best, consistent, and spatially explicit information for operational drought monitoring.
