A look at the late, great campaign for measuring mid-continent greenhouse gases One day in March 2000, a Cessna 172 took off from a little airstrip in Ponca City, Oklahoma. The intent: Measure air samples of dried aerosol particles at nine different altitudes to determine their light-scattering and absorption properties. The data were collected on behalf of the In Situ Aerosol Profiles (IAP) [...]

ARM Data Flow: A Look Back

ARM Data Flow: A Look Back

Published: 19 September 2016

Feature Stories and Releases

From its inception in 1990, the Atmospheric Radiation Measurement (ARM) Climate Research Facility has focused on four topics: science, instruments, sites, and data. Over time, the science focus evolved, expanding from radiative transfer to atmospheric processes and then to improved parameterizations for models. Instruments got more robust and numerous. The number of sites grew; ARM added mobile [...]
