mean precipitation provided by GNIP and NCEP/NCAR reanalysis data provided by Noaa-cires and discussed the main water vapor sources in the Yangtze River Basin. Maps of Rainfall Percentile, Annual Cycle of Average Products that are routinely available are: CMORPH - CPC MORPHing Global Precipitation Analysis. This dataset contains all hourly precipitation data from the National Centers for Environmental Prediction (NCEP) stations. Information on the NCEP/NCAR project can be obtained at the official website. All three precipitation products are produced by optimally merging estimates computed from microwave, infrared, and sounder data observed by the international constellation of precipitation-related satellites, and precipitation gauge analyses. Data analysis routines, including a bias correction of the radar estimates using rain gage data, have been adapted by NCEP on a national 4-km grid from algorithms developed by OH and executed regionally at NWS River Forecast Centers (RFC). Although the initial plan is to reanalyze the data for a 40-year period (1957-1996), production has gone back to 1948 and going forward continuously. Results are available at 6 hour intervals. The analyses are are on a 2.5 x 2.5 degree latitude/longitude grid and extend back to 1979. National Centers for Environmental Prediction, Preliminary GPCP Geostationary Satellite Precipitation Data Center. Still, it is still a 'first generation' product. Data is in netCDF files, each year, separate file; Download . NOTE: Due to a hardware failure, GPCP SG V2.2 and 1DD V1.2 have ceased production. This dataset contains the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) 4 KM GRIB gage-only analysis ("GAG") data. Current Palmer Drought Severity Index Percentiles Map (by State) Additional Precipitation Needed to Bring Palmer Index to -0.5 Inches. Teleconnection Patterns, El Niño's Influence on United States Precipitation Amounts, El Niño, La Niña, Neutral - Snowfall for Selected Cities, United States Temperature & Precipitation Trends, U.S. If the TRMM data can be shown to correspond closely to the NCEP temperature analyses, then the much longer record of NCEP data can be used to estimate certain climate statistics, such as interannual variability of the brightband altitude. This analysis merges two data sources that are currently being collected in real-time by OH and NCEP. This data set consists of monthly averaged precipitation rate values (mm/day). The pentad dataset consists of 73 pentads per year with the 12th pentad covering Feb 25-Mar 1 … Then, simulation results of the data were appraised based on quantitative evaluation indices of model simulation and uncertainties. CMAP refers to a collection of precipitation data sets, though the 2.5°x2.5° global monthly version is probably the most widely used. The Global Forecast System (GFS) is a weather forecast model produced by the National Centers for Environmental Prediction (NCEP). Here we use more realistic settings: the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS), running at a low resolution, and the TMPA data as the precipitation observations. The resolution of the global Reanalysis Model is T62 (209 km) with 28 vertical sigma levels. The dataset variables have been generated using the. This analysis merges two data sources that are currently being collected in real-time by OH and NCEP. Report intervals range from hourly to 3 hourly. America Daily Precipitation Analyses, Global Mosaic done at NCEP within an hour of receiving any new hourly/6-hourly data from one or more RFC. ... CA_SST: Constructed Analog Sea Surface Temperature Forecasts. (Percentile) with ENSO Episodes Noted (1955-1996). Global Precipitation Climatology Project monthly precipitation dataset from 1979-present combines observations and satellite precipitation data into 2.5°x2.5° global grids. NCEP Generated Products: Air Quality Model (AQM) Climate … Daily Gridded CPC Precipitation for 1979 to present. Monthly and pentad global gridded precipitation means. There are several potential sources of precipitation data that could be used for precipitation analyses including 24-hr "first order" WMO GTS sites (near-real-time), 24-hr SHEF-encoded precipitation reports received via AFOS from the River Forecast Centers (near-real-time), hourly GOES/DCP and CADAS precipitation reports (near-real-time), hourly and 24-hr NCDC cooperative reports (non-real-time), and perhaps many other sources (e.g. These gridded data were compared with observed data. Precipitation Needed to Bring Palmer Index to -0.5 Inches, Current A prototype, real-time, hourly, multi-sensor National Preciptation Analysis (NPA) has been developed at NCEP in cooperation with the Office of Hydrology (OH). NCEP 'Stage II' refers to the real-time, hourly, multi-sensor National Precipitation Analysis (NPA) developed at the National Centers for Environmental Prediction (NCEP) in cooperation with the Office of Hydrology (OH). Seasonal Rainfall (1955-1996), Seasonal Total Rainfall That data was done at 8 times daily in the model, … Most precipitation data sets may be categorized into one of three broad categories: gauge data sets (e.g. Stations that reported at standard or incremental times are also included in the various NESOB 1997 precipitation composite datasets. This data set has been produced by blending gauge and infrared and microwave satellite estimates of precipitation. Indices, Monitoring Atlantic Daily Precipitation Analyses, South Moisture Monitoring, Northern Hemisphere Daily Snow Cover Data, Experimental Daily NWS/Cooperative Observer Snow Depth and Snowfall Graphics and Data, United States NCEP Reanalysis (R2) NCEP-DOE Reanalysis II (R2) is an improved version of the NCEP-NCAR Reanalysis I (R1). This analysis merges two data sources that are currently being collected in real-time by OH and NCEP. Mosaicked into a national product at NCEP, from the regional hourly/6-hourly multi-sensor (radar+gauges) precipitation analyses (MPEs) produced by the 12 River Forecast Centers over CONUS. (.
