This data release is the update of the U.S. Geological Survey (USGS) - ScienceBase data release Bera (2021b), with the processed data for the period October 1, 2019, through September 30, 2020. This data release describes the watershed data management (WDM) database file WBDR20.WDM. The WDM database file WBDR19.WDM (Bera, 2020b) is updated with the quality-assured and quality-controlled meteorological and hydrologic data for the period October 1, 2019, through September 30, 2020, following the guidelines documented in Bera (2017) and is renamed as WBDR20.WDM. Meteorological data other than precipitation (wind speed, solar radiation, air temperature, dew point temperature, and potential evapotranspiration) are copied from ARGN20.WDM and stored in this WDM file. Bera (2021a) describes the processing of the meteorological data in the database file ARGN20.WDM. Data in dataset number (DSN) 107 and 801?811 are used in comparisons of precipitation data. DSN 107 contains hourly precipitation data from tipping bucket rain gages collected at Argonne National Laboratory at Argonne, Illinois. DSN 801-811 contains the processed Next Generation Weather Radar (NEXRAD)-Multisensor Precipitation Estimates (MPE) data from 11 NEXRAD?MPE subbasins in the West Branch DuPage River watershed as described in Bera and Ortel (2018). The data are downloaded and uploaded daily into a WDM database that is used for the real-time streamflow simulation system. Data from DSN 107 and 801-811 are copied from this WDM and stored in WBDR20.WDM. DSN 107 and 801-811 are updated with the data through September 30, 2020. Data in DSN 4031 (water-surface elevation from West Branch DuPage River at Fawell Dam) is updated through September 30, 2020, similarly (Bera, 2017). During October 1, 2019, through September 30, 2020, the daily total rainfall (in the water year summary for water year 2020) from the rain gage using the HOBO logger did not equal the sum of the instantaneous values pulled from the USGS National Water Information System database (NWIS) for several days. This is due to multiple tips occurring within the same minute. NWIS only counts the first tip and ignores any other tips that occur within the same minute. HOBO loggers only record the time of a tip and the data is post processed to apply midnight time stamps and backfill 5- or 15-minute instantaneous values into the data log. The multiple tips occurring in the same minute are accurate, thus so is the daily total in the water year summary table. Table 1 shows the list of station(s) using the HOBO logger that had different daily total rainfall in the Water Data Report than those computed from the data pulled from NWIS. The days with the difference of 0.03 inches or more are filled with the nearby stations as listed in Table 1. The rain gages using DCP loggers provide a value or data point every 5 or 15 minutes and do not show any difference from the instantaneous values pulled from NWIS. The complete list of missing precipitation data period and the nearby stations used to fill in those missing periods from October 1, 2019, through September 30, 2020, is given in the Table 2. Both Table 1 and Table 2 are in comma separated values (CSV) file format. The list of snow affected days of precipitation data and the missing and estimated period of the stage and flow data in WBDR20.WDM database during the period October 1, 2019, through September 30, 2020, are given in the USGS annual Water Data Report at https://wdr.water.usgs.gov.
