SEARCH - A Study of Environmental Arctic Change
NOAA and Environment Canada are cooperating closely under the aegis of NOAA's SEARCH program. NOAA/ESRL and Environment Canada have set up an integrated system for monitoring aerosol optical properties, similar to systems at other NOAA/ESRL long-term monitoring sites, e.g., Mauna Loa, HI and Barrow, AK.
ALT Aerosol Properties Plots
Statistical Summary Plots - Multi-year record of final aerosol and atmospheric property data.Do not quote or cite.
Atmospheric Properties
These plots are designed to provide a quick look at the measured aerosol properties. They display raw unedited data, but known corrections for instrument errors have been applied.
