Stratospheric Aerosol Measurement (SAM) II sensor aboard the Nimbus 7 spacecraft. The first 6 months of data were previously reported by McCormick in NASA Reference Publication entitled "SAM II Measurements of the Polar Stratospheric Aerosol, Volume I - October to April " Similarly, the second 6 months of data, cov-. The Stratospheric Aerosol Measurement II (SAM II) experiment flew aboard the Nimbus-7 spacecraft and provided vertical profiles of aerosol extinction in both the Arctic and Antarctic polar regions. The SAM II data coverage began on Octo and extended through Decem until SAM II was no longer able to acquire the Sun. Typical values of aerosol extinction at the SAM II wavelength of _m for this time period are I to 3 times km-1 in the main stratospheric aerosol layer. Optical depths for the stratosphere are about Polar stratospheric clouds (PSC's) at altitudes of about 22 km were observed during the Arctic winter at various times and locations.

SAM 2 led to a subsequent series of instruments to study aerosols over the poles, the most recent of which is the Stratospheric Aerosol and Gas Experiment III, placed on the International Space Station in March SAM II ‐ Sun‐synch / Nimbus 7 Single channel @ 1 m Polar Stratospheric Clouds SAGE I ‐ Inclined/AEM‐2 Ozone, Aerosol, NO2 Pre‐decline ozone baseline SAGE II ‐ Inclined/ ERBS + Water Vapor Ozone Trends, Extreme aerosol variability SAGE III • File Size: 8MB.

A global climatology of stratospheric aerosol is created by combining nearly a decade ( and ) of contemporaneous observations from the Stratospheric Aerosol and Gas Experiment (SAGE I and II) and Stratospheric Aerosol Measurement (SAM II) instruments. One goal of this work is to provide. A global aerosol climatology is evolving from the NASA satellite experiments SAM II, SAGE I, and SAGE II. In addition, polar stratospheric cloud (PSC) data have been obtained from these experiments over the last by: backscatter, color ratio, and aerosol depolarization ratio for polar stratospheric clouds and stratospheric aerosols. The data used are from 19 separate flights spanning the dates of December 2, to Ma over the Arctic stratosphere from the altitude range of 16 to 27 km, where polar stratospheric clouds are usually found.
