• L3SIST_D01M.tif: Sets the output file name.

• gdal_calc: gdal command to perform calculations on the data
• -A: Set the file name used in the formula to "A."
• GC1SG1_20220309D01D_T0428_L2SG_SIPRK_3000_SIST_QA_flag.tif: File name to be calculated
• --A_band=2: Set the order in GeoTIFF where QA_flag is stored
• --outfile: Set any output file name for calculation results
• --calc: Set up calculation formulas
• (A >> 4) & 7: Shift the bit information by 4 bits to the right. Only the upper bits are left. Also, extract the 4th-6th bit by bit AND calculation.
• < 7: Extracts data where the extracted 4-6 bits have a snow cover of 111(7) or less.
• (A >> 2) & 1: Shift the bit information by 4 bits to the right. Only the upper bits are left. Also, the second bit is extracted by bit AND calculation.
• == 0: Extracts data in which the extracted 2 bits have no clouds of 0 (zero).
• * 1: If all the conditional expressions are satisfied, "1" is set. For convenience, "*1" is set, but it does not matter if "*1" is not set, since "1" will be set if the expressions are satisfied.

• gdal_calc: gdal command to perform calculations in the data
• -A, -B: Set "A" and "B" as file names to be used in formulas

• (A <= 59999) * (B == 1) * A: If the A data are within the valid range and the B data are "1," the A value is left unchanged. Calculations using slope/offset are also possible.
• (A <= 59999) * (B == 0) * 65535: The data where A data are within the valid range and B data are "0" are assigned to the invalid value.
