• L3AROT_202207_01M.tif: Set the output file name.

• gdal_calc: gdal command to perform calculations in the data
• -A: Set the file name used in the formula to "A"
• GC1SG1_20220916D01D_T0528_L2SG_ARNPK_3003_AROT_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) & 3) < 3): First, shift the bit information by 4 bits to the right. Only the upper bits are left. Also, calculate the and (& 3) of bits and extract the 4th-5th bit, leaving fewer than 11(3) bits.
• (((A >> 13) & 1) == 0): First, shift the bit information by 13 bits to the right. Only the upper bits are left. Also, calculate the and (& 1) of the bit and extract the 13th bit. The value of the 13th bit of "0" is left.
• ((A & 1) == 0) * 1: If the value of the 0 bit (valid value) is "0" in the and (& 1) calculation of the bit, it is left. If the conditional expression is satisfied, "1" is set.
• --NoDataValue: Set an invalid value

• gdal_calc: gdal command to perform calculations in the data
• -A, -B: Set "A" and "B" as file names to be used in formulas
• GC1SG1_20220916D01D_T0528_L2SG_ARNPK_3003_AROT_QA_flag.tif: Set to "A" the name of the file to be calculated
• L2ARNP_AROT0528D01D_QA.tif: Set the file name from which flags are extracted to "B."
• --A_band=1: Set the order in GeoTIFF where AROT is stored
• --outfile: Set any output file name for the calculation results
• --calc: Set up calculation formulas
• (A <= 50000) * (B == 1) * A: If the A data is within the valid range and the B data is "1", the A value is left unchanged.
• (A <= 50000) * (B == 0) * 65535: Data containing A data within the valid range and B data "0" are assigned to the invalid value.
• (A > 50000) * (B == 0) * 65535: Data with A data outside the valid range and B data "0" are assigned to invalid values.
• (A > 50000) * (B == 1) * 65535: The data containing A data is outside the valid range and B data is "1" are assigned to invalid values.

• gdal_translate: Format conversion commands.
  For a description of the commands, see "3) gdal command example for Level-3 product conversion."
• gdal_calc: Use gdal command to perform calculations on the data
  In the first gdal_calc, values outside the valid range of the QA_flag are set to "0," and the values within the valid range are set to "1".
  The second gdal_calc is as follows
• -A, -B: Set "A" and "B" as file names to be used in formulas

• --outfile: Set any output file name for the calculation results
• --calc: Set up calculation formulas
• (A <= 50000) * (B == 1) * A: If the A data is within the valid range and the B = "1," the A value is left unchanged. Calculations using slope/offset are also possible.
• (A <= 50000) * (B == 0) * 65535: Data with A data within the valid range and B = "0" are assigned to the invalid value.
• (A > 50000) * (B == 0) * 65535: Data with A data outside the valid range and B = "0" are assigned to invalid values.
• (A > 50000) * (B == 1) * 65535: The data with A data outside the valid range and B = "1" is assigned to the invalid value.
