Grid-to-Grid daily simulated soil moisture 1964-2018, at selected UK Soil Moisture Databank sites.

<p>This dataset contains Grid-to-Grid (G2G) daily simulated soil moisture time-series at selected UK Soil Moisture Databank (UKSMD)&nbsp;sites. It was created to&nbsp;facilitate an evaluation of G2G simulated soil moisture against the UKSMD neutron probe soil moisture observations (Bell et al., 2022).&nbsp;</p> <p>G2G (Bell et al., 2009) is a national-scale gridded hydrological model, which has been widely applied to simulate river flows&nbsp;and more recently soil moisture. Here, the model was run at 1km resolution from 01/01/1964 - 16/12/2019&nbsp;across Great Britain. Simulated soil moisture time-series are provided for the 1km grid-cells closest to selected UKSMD&nbsp;site locations. The G2G simulates vertically-integrated soil moisture&nbsp;in units of mm/m. For further explanation of G2G soil moisture, please see Kay et al., 2022&nbsp;(https://iopscience.iop.org/article/10.1088/1748-9326/ac7a4e).&nbsp;&nbsp;</p> <p>The data is provided as two plain text files:</p> <p>1)&nbsp;g2g_soilmoist_1964_2018.txt contains&nbsp;the simulated soil moisture values. The first three columns specify the simulation date (day, month, year). Subsequent columns are soil moisture (mm/m) time-series at&nbsp;each site, with the UKSMD site ID given as column headers.&nbsp;</p> <p>2) site_locations.csv contains the locations of the UKSMD sites.&nbsp;In some cases there were multiple tubes&nbsp;with slightly different locations within a larger site, and here we are providing the location of the specific tube used.&nbsp;Columns specify: SITE_NAME (the site ID),&nbsp;TUBE_NAME (the tube number), EASTING and NORTHING (easting and northing in British National Grid). The site ID and tube names used in this document are consistent with the UKSMD&nbsp;documentation.&nbsp;</p> <p>References:</p> <p>Bell, V. A., Kay, A. L., Jones, R. G., Moore, R.
