Definition
- The Mobile Automatic Scanning Photometer (MASP) began operation in March 1979 and has provided continuous data since August, 5, 1979. This database contains information from August 5, 1979, to September 2, 1994. Measurements of the attenuation of direct solar radiation are taken by the photometer for different wavelengths using 12 filters. Five of these filters (i.e., those for 428 nm, 486 nm, 535 nm, 785 nm, and 1010 nm wavelengths, with respective half-power widths of 2, 2, 3, 18, and 28 nm) are suitable for monitoring variations in the total optical depth of the atmosphere.
