Concept for Arctic Atmospheric ObservatoriesTo understand the Arctic atmosphere it is necessary to have detailed, continuous, co-located measurements of clouds, aerosols, radiation, atmospheric vapor, surface fluxes, and standard surface and upper air meteorological observations. Observations should be sufficient to monitor AND understand mechanisms. Understanding mechanism requires data sets that can (1) Improve models (2) validate satellite observations (3) facilitate process studies.
Clouds and aerosols in the Arctic have a major influence on surface radiation budgets and resulting surface temperatures, ice ablation/melt rates, and the onset of the annual snow melt season.
Major components of an Arctic Atmospheric Observatory are active cloud sensors, passive and surface aerosol sensors, broadband radiation fluxes (up and down), surface fluxes, and spectral radiometry.
Intensive Observatories should also have components that integrate them into less intensive but more widely distributed networks such as BSRN, CRN, GAW and others.
Upper and lower atmosphere measurements should be integrated.
