DMSP Satellite Total Ozone And Calibrated Radiance Grids

DMSP satellite data provides total column ozone and calibrated radiance measurements from the Multichannel Filter Radiometer. The collection includes observations from four DMSP block 5D-1 satellites spanning from March 1977 to February 1980. Data was processed and calibrated at Lawrence Livermore National Laboratory.

Use Cases

• Analyze historical trends in total ozone column values across polar stereographic grid points.
• Calibrate modern ozone retrieval algorithms using the 9.6 micrometer band radiance data from the MFR instrument.
• Compare daily ozone grid files from up to four different DMSP satellites for cross-validation.
• Study diurnal variations using daytime and nighttime MFR sensor observations.
• Map ozone distribution on a 67 x 67 point polar stereographic grid for each hemisphere.

Strengths

• Up to 67,500 potential observations per 24-hour period by satellite.
• Data spans nearly three years from 1977 to 1980 across four satellite missions.
• Ozone grid point values are expressed to the nearest tenth of a m-atm-cm.

Limitations

• Data format is legacy 6250-bpi magnetic tape, requiring specialized hardware or conversion.
• Temporal coverage ends in February 1980, providing no recent observations.
• Sample size and exact row counts are unspecified in the provided description.
