      The TMY3 file format has some additional fields that the TMY2
    format did not have. The "liquid precipitation depth" is defined as
    the amount of liquid precipitation observed at the indicated time
    for the period indicated while the "liquid precipitation quantity is
    defined as the period of accumulation for the liquid precipitation
    depth output. As far as converting between the two file types is
    concerned there are two issues. There may be some utilities
    available to convert the format of a file from TMY2 to TMY3. However
    even if you convert the format, the far bigger difficulty is in
    getting the data that would have to be added to the TMY3 file
    format. Finding average hourly rain/snow fall data for a particular
    location is probably not an easy thing to do.<br>
