Q
    Accumulated days of half-month composite snow coverage flag (CSF) products differ depending on sites. Do you have any information about composite days?
    A

    Please use detailed information stored in HDF files. HDF files store number of clear days for half a month (Clear_Day_NUM, for example, number of days distinguished as clear regions for 15 days) and number of snow days (Snow_Day_NUM, number of snow coverage regions for 15 days as well).
