Title: The NOAA Climate Monitoring Diagnostics Laboratory (CMDL) Aerosol Data from the NOAA Climate Diagnostics Center via WWW
Description:
Abstract:
The NOAA Climate Monitoring and Diagnostics Laboratory (CMDL) address on the WWW is 'http://www.cmdl.noaa.gov/'. This data set records light-scattering coefficient and condensation nuclei concentration measurements, taken from four monitoring stations at remote locations. The data are collected by the Geophysical Monitoring for Climatic Change (GMCC) Program to measure the concentrations and characteristics of gaseous and aerosol species in the atmosphere. The mission of the GMCC program is to detect any long-term trends in the concentrations of these species caused by anthropogenic or natural sources, and to assess possible climatic effects that may result from these changes. The four monitoring stations are located at 1) Barrow, Alaska; 2) Mauna Loa, Hawaii; 3) Cape Matatula, American Samoa; and 4) Amundsen-Scott Station, South Pole, Antarctica. All are located on approximately the same longitude and are situated to allow sampling of Arctic, northern midtropical, southern midtropical, and Antarctic air. The stations are located at remote sites to minimize the effect of local pollution sources. At each station, a condensation nucleus counter measures the condensation nuclei concentration, and nephelometers measure the scattering portion of extinction due to aerosol particles in the atmosphere at four wavelengths, 450, 550, 700, and 850 nm. The output signal of each instrument is sampled once per second, and data are stored on magnetic tape in the form of 1-min and 1-hour means. The data are then edited on an hourly basis to eliminate bad data, fill missing data from backup instruments, and apply final calibrations. A nearly continuous record is available from the Barrow station since 1971, from Mauna Loa since 1974, from Samoa since 1977, and from the South Pole since 1974. All GMCC aerosol data are available from the principal investigator in magnetic tape, printout, graphic, or microfiche format.
