Hi, I am wondering about the best method for converting some previously fixed-distance (2km) gridded radar data to a more coarse, earth-fixed grid. The data consists of a 151 x 151 pixel array of rain estimates. I know the center of each 2 km pixel with respect to lat/lon and the middle pixel (75,75) is the location of the radar. I want to choose, say a 0.25 or 0.5 degree grid centered over the data and resample the data to that grid. Note that I have missing data near the center of the original grid (due to the radar's cone of silence) and at ranges beyond 150 km from the center of the grid. Right now I am doing a simple averaging of all the 2 km pixels that fall within a given earth-grid box, but I need to investigate if a more robust approach is appropriate. Thanks, David
