  • IEM :: Reanalysis Data
    Images Hi res Live Loops Recent Movies Cool Lapses IEM Reanalysis IEMRE IEM Reanalysis is an effort to provide a regular dataset of Iowa Environmental Data without many of the problems associated with single site observations The IEM will continue to provide single site observational data but for some purposes this dataset will be easier to work with No dataset is perfect and this dataset is provided without warranty Why do this Previously the IEM has only provided raw observations with limited quality control checks in place Quality control is hard Many times users are simply looking for something close and perhaps not as perfect as high quality sensor observations can be Producing a gridded analysis is one way to produce a dataset from point observations which can be sampled as a means of spatial interpolation Isn t this a duplication of effort While there are other reanalysis type projects out there with data freely available many times their data does not update in near real time and does not include many of the datasets the IEM uniquely collects We may also produce an analysis on sub hourly timescales Data Flow 1 Input Datasets NCEP Stage IV Precipitation This is an hourly gridded product with precipitation estimates derived by RADAR and then bias corrected by gauge data The IEM caches the grib data and makes hourly plots available here MRMS Precipitation Currently this is only used to populate a daily total in a dedicated netcdf file ASOS AWOS Daily Summaries NWS Daily Climate Summaries HRRR MERRA NARR Daily Solar Radiation NWS COOPerative Observations Manually QC d Iowa COOP data from Iowa s State Climatologist NCDC QC d COOP Data 2 IEM ReAnalysis Gridded Datasets Daily Maps of Gridded Variables View a smoothed or gridded plot of IEMRE data Download the
