GPM Ground Validation Daily Precipitation OLYMPEX

The GPM Ground Validation Daily Precipitation Olympic Mountain Experiment (OLYMPEX) dataset consists of a single netCDF-4 data file containing estimates of daily precipitation, both rainfall and snowfall amounts, on a 1/32 degree spatial resolution grid covering the extent of the OLYMPEX field campaign region in the Olympic Mountains of the state of Washington. This data product was created for the GPM Ground Validation OLYMPEX field campaign. These VIC precipitation estimates are based on NOAA WSR-88D radar and rain gauge data incorporated in NOAA’s National Severe Storms Laboratory (NSSL) local gauge bias-corrected radar quantitative precipitation estimation (QPE) model (product Q3GC) and the Mountain Mapper QPE model (product Q3MM). The VIC hydrology model was used to invert the snow water equivalent (SWE) values to derive precipitation through adjustment of the precipitation-weighting factor on a grid cell by grid cell basis. The VIC precipitation data are available from October 1, 2015 through April 30, 2016.

GPM地面验证每日降水量奥林匹克山实验（OLYMPEX）数据集由一个包含每日降水量估计的单个netCDF-4数据文件组成，包括降雨和降雪量，该数据以1/32度空间分辨率网格覆盖华盛顿州奥林匹克山脉OLYMPEX实地考察区域。此数据产品专为GPM地面验证OLYMPEX实地考察活动创建。这些VIC降水量估计基于NOAA WSR-88D雷达和雨量计数据，这些数据被纳入NOAA国家严重风暴实验室（NSSL）本地校准的雷达定量降水估计（QPE）模型（产品Q3GC）以及Mountain Mapper QPE模型（产品Q3MM）。VIC水文模型被用于将雪水当量（SWE）值反演，以通过调整网格单元上的降水加权因子来推导降水量。VIC降水量数据自2015年10月1日起至2016年4月30日止均可获得。
