Barnes analysis method blends observations from: Gauge reports. AFWA Geostationary IR satellite precipitation estimate. AFWA CDFSII precipitation estimate. DMSP SSM/I & SSMI/S rainrate estimates (Tropics only) Climatology. The surface observations are retrieved from the CDMS database. The data is used to calculate rainfall based on the current or past weather reports. The processing accounts for as many 6 and 12 hourly rain gauge amounts as possible, using the information provided by each station. The processing includes special logic to handle different reporting practices of various countries. The rain rates from the SSMIS processing generates a 3 hourly SSMIS-based estimate. The climatological precip amount, climatological precip per precip day amounts, and the climatological RTNEPH cloud amounts and the actual CDFSII total cloud amounts are used to generate a CDFSII based precip estimate. The GEOPRECIP rain rates and rank values are read in to generate a precipitation estimate. The rank values provide a measure of the goodness of the estimate. (1-better than SSM/I, 2-better than present weather estimate, 3-better than CDFS-II based), 3- default value of GEOPRECIP estimate, 5-worse than climatological estimate) Finally, all the different estimates are merged based on the specified hierarchy, for each point on the grid. Depending on the cycle time, parse the 6 hour or 12 hour precip amounts into 3 hour amounts. Validate the 3 hourly real precip amounts and estimates and generate a merged precip fied using a modified barnes objective analysis technique.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
