Gridded model estimates of nitrate-N stored in the vadose (unsaturated) zone. This dataset presents annual gridded estimates of nitrate stored in the vadose zone for 1900 - 2000 on a 0.5 degree grid (units: kg N/grid cell). Data are supplied as a single netCDF for all years. This data was derived by Ascott et al. (2017). Global models of depth to groundwater table, subsurface porosity and groundwater recharge were used to derive estimates of nitrate travel time in the vadose zone. The travel time was combined with annual estimates of nitrate leaching from the base of the soil zone for 1900 - 2000 to estimate total nitrate stored in the vadose zone.

The IGRF is a global model of the geomagnetic field. It allows spot values of the geomagnetic field vector to be calculated anywhere from the Earth's core out into space. The IGRF is generally revised every five years by a group of modellers associated with the International Association of Geomagnetism and Aeronomy (IAGA).

The World Magnetic Model (WMM), produced jointly with the US National Oceanographic and Atmospheric Administration's National Geophysical Data Center, is the standard model in UK Ministry of Defence and US Department of Defense navigation and attitude reference systems and is also used widely in civilian navigation systems. The model is also used on marine and aviation charts and is revised every five years.

DiGBcoast v1.0, is a new supranational dataset documenting three decades of coastal change across Great Britain mainland (England, Scotland, and Wales) including the isle of Wight and Anglesey. This dataset has been produced using the publicly available optical Landsat-5,8 and Sentinel-2 missions over the period between 1984 to 2022 (38 years). It includes instantaneous waterlines and instantaneous tidally corrected to Mean Sea Level shorelines. DiGBcoast is made available to the public as free and open interactive data to support future coastal research and management across Great Britain.
