Measurement of Air Pollution from Satellites (MAPS)

NSSDCA ID: 1981-111A-04

Mission Name: STS 2/OSTA 1
Principal Investigator:Dr. Henry G. Reichle, Jr.


The Measurement of Air Pollution from Satellites (MAPS) experiment measured for about 35 h the distribution of carbon monoxide in the middle troposphere, upper troposphere, and lower stratosphere over the region from 38 deg N to 38 deg S during both daytime and nighttime. The performance of the MAPS instrument under various temperatures and other orbital conditions indicated the efficiency of using orbiting spacecraft to measure environmental quality. The MAPS equipment consisted of an electro-optical head, an electronics module, a digital tape recorder, and an aerial camera. The core of the MAPS instrument was a nadir-viewing gas filter radiometer operating at the 4.67-micrometer CO band. The instantaneous field of view was approximately 20 by 22 km. The equipment was coupled to a cold plate and mounted on the experiment pallet shelf. The aerial camera was mounted alongside the MAPS electro-optical head to provide information on cloud cover and the terrain over which the data were gathered.
