Mean monthly outgoing surface longwave radiation modelled using the 1" DEM-S - 3" mosaic data

Mean monthly solar radiation was modelled across Australia using topography from the 1 arcsecond resolution SRTM-derived DEM-S and climatic and land surface data. The SRAD model (Wilson and Gallant, 2000) was used to derive:\n*\tIncoming short-wave radiation on a sloping surface\n*\tShort-wave radiation ratio (shortwave on sloping surface / shortwave on horizontal surface)\n*\tIncoming long-wave radiation\n*\tOutgoing long-wave radiation\n*\tNet long-wave radiation\n*\tNet radiation\n*\tSky view factor\nAll radiation values are in MJ/m2/day except for short-wave radiation ratio which has no units. The sky view factor is the fraction of the sky visible from a grid cell relative to a horizontal plane.\n\nThe radiation values are determined for the middle day of each month (14th or 15th) using long-term average atmospheric conditions (such as cloudiness and atmospheric transmittance) and surface conditions (albedo and vegetation cover). They include the effect of terrain slope, aspect and shadowing (for sun positions at 5 minute intervals from sunrise to sunset), direct and diffuse radiation and sky view.\n\nThe data in this collection are available at 3 arcsecond resolution as single (mosaicked) grids for Australia in TIFF format.\n\nThe 3 arcsecond resolution versions of these radiation surfaces have been produced from the 1 arcsecond resolution surfaces, by aggregating the cells in a 3x3 window and taking the mean value.\n\nThe 1 arcsecond tiled data can be found here: https://data.csiro.au/dap/landingpage?pid=csiro:18335 .
