Olivier Prat: Highlights 2015
Reference Environmental Data Records
- Merged radar quantitative precipitation estimates (QPEs) from the high-resolution NEXRAD reanalysis over CONUS with rain-gauge observations (GHCN-D, HADS, CRN). Performed bias-adjustment of the radar-only product at the daily and hourly scale for the period 2002–2011. Currently implementing and testing techniques for optimally merging the rain gauge datasets and the radar-only estimates (inverse distance weighting, kriging, and variants).
- Work is progressing on the evaluation of using quantitative precipitation estimates (QPEs) derived from satellite observations to derive long-term global precipitation characteristics at fine spatial and temporal resolution. This is part of a broader effort to develop Reference Environmental Data Records (REDRs) for precipitation. Three papers have been published in the past year.
- Lead author of a manuscript published in Hydrology and Earth System Sciences (HESS) on the evaluation of multi-sensor precipitation estimates over CONUS.
