thanks @dave for your reply,
I had tried your solution earlier, it can calculate T air well for small area.
But still can’t works when I put all my study area in. The aoi.shp already clips for 1500m from the edges lulc raster, and my air blending area set for only 100m. The result as below.
- The one in the middle is the success one (for a town scale).
- The pink line is the edge of area of interest.
- The black polygon is the Tair rater; grayscale is Tair nomix raster.
- The bottom one are lulc raster.
As the T air shows a rectangular area, does it means the lulc raster need to cover all rectangular extent area of aio.shp?
