Noise characteristics of the AVHRR infrared channels
International Journal of Remote Sensing 10:4-5 (1989) 637-644
Abstract:
Limitations on the precision of digitized data are identified and discussed. Apart from calibration errors, these sources of uncertainty can be divided into three types of noise; digitization, Gaussian and periodic, each of which behaves differently when data is averaged. An attempt is made to separate and quantify these contributions in the infrared channels (3, 4 and 5) of various AVHRR instruments. Typical values of total noise for these channels are also obtained. © 1989 Taylor & Francis Ltd.REFERENCE MODEL FOR CH4 AND N2O AND TRENDS

Proposed reference models for nitrous oxide and methane in the middle atmosphere
Advances in Space Research 7:9 (1987) 49-62
Abstract:
Data from the Stratospheric and Mesospheric Sounder (SAMS) on the Nimbus 7 satellite, for the three years from January 1979-December 1981, are used to prepare a reference model for the long-lived trace gases methane (CH4) and nitrous oxide (N2O) in the stratosphere. The model is presented in tabular form on seventeen pressure surfaces from 20 to 0.1 mb, in 10° latitude bins from 50S to 70N, and for each month of the year. The means by which the data quality and interannual variability, and some of the more interesting globally and seasonally variable features of the data are discussed briefly. © 1987.Satellite-borne measurements of the composition of the middle atmosphere
