    Dear Navlist members,
    I am currently working with climate data given in a database for the whole world.
    Resolution is 1 deg latitude/ 1 deg longitude cells which makes 180 * 360 cells overall.
    Since for every cell a number of year's data is available it is a lot of material.
    My work requires only data for those cells on land.
    Does anybody know a quick and easy way to determine which cells are relevant (i.e. on land, not ocean)?
    This should be a standard procedure for many purposes, however I couldn't find anything helpful yet.
    Your advice will be much appreciated.
