Watershed Data Management (WDM; Flynn and others, 1995) database file WBDR13.WDM is updated with the quality-assured and quality-controlled meteorological and hydrologic data for the period October 1, 2013, through September 30, 2016, following the guidelines documented in Bera (2017) and is renamed as WBDR16.WDM. Meteorological data other than precipitation (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration) were copied from ARGN16.WDM and stored in this WDM file. Errors have been found in each of ARGNXX.WDM prior to Water Year (WY) 2023. XX represents last two digits of a WY. A WY is the 12-month period, October 1 through September 30, in which it ends. The database file WBDR16.WDM contains erroneous meteorological data and related flag values thereby. The database file WBDR16.WDM is replaced with WBDR22.wdm (Bera, 2024b). This is version 1.1 of this data release with the corrected meteorological data copied from ARGN23.wdm (Bera, 2024) for the period January 1, 2007, through September 30, 2022. This database file also contains the quality-assured and quality-controlled hydrologic data for the period January 1, 2007, through September 30, 2022, processed following the guidelines documented in Bera (2017). The complete list of datasets in WBDR22.WDM database and the detail attributes of each of these datasets is given in table 1. The complete list of missing periods of the precipitation data and the nearby stations used to fill in those missing data during the period October 1, 2013, through September 30, 2016, is given in table 2. The list of snow affected days of precipitation data and the missing and estimated period of the stage and flow data in WBDR22.WDM database during the period October 1, 2013, through September 30, 2016, are given in USGS annual Water-Data Report at https://wdr.water.usgs.gov. To open WBDR22.WDM file user needs to install Sara Timeseries utility described in the section "Related External Resources".
