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

TL;DR: In this paper, the authors analyzed the potential role played by unusually warm Indo-Pacific SS, where unusual is defined as a 1-in-6 year event, and showed that strong El Ninos may be followed by warm western Pacific SST conditions, which can lead to creating conditions conducive for successive and potentially predictable droughts in Southern Africa and Eastern Africa.

Comparing Multiple Precipitation Products against In-Situ Observations over Different Climate Regions of Pakistan
TL;DR: Various state-of-the-art gridded satellite precipitation products have been derived from remote sensing and reanalysis data and are widely used in hydrological studies, suggesting similar dynamics; however, statistical metrics suggested that the performance of these products varies from north towards south.

Mapping rice areas with Sentinel-1 time series and superpixel segmentation
TL;DR: One of the first methods that shows the potential of C-band SAR data for accurate and timely mapping of rice-growing areas is developed, using superpixel segmentation to create spatially averaged backscatter time series, which is robust to speckle and reduces the amount of data to process.
