Data obtained at the ACRF sites are freely available to users worldwide through the ACRF Data Archive. In August, the ACRF added another entry point to its data collection by registering the ARM Program and Data Archive as components within the Global Earth Observation System of Systems (GEOSS). This web-based decision-support tool links together existing [...]

The Orbiting Carbon Observatory, or OCO, is a National Aeronautics and Space Administration (NASA) Earth System Science Pathfinder (ESSP) mission designed to make precise, time-dependent global measurements of atmospheric carbon dioxide from an Earth-orbiting satellite. Starting in July and lasting through 2010, the ACRF Southern Great Plains (SGP) site is hosting the mobile laboratory for [...]

To analyze cloud properties, ARM scientists use data from an instrument called a ceilometer. This instrument transmits pulses of light into the sky and receives return signals to measure scattered radiation, cloud base heights, and visibility. In preparation for a pending upgrade to the instrument, operations staff completed a field campaign at the ACRF Southern [...]

One instrument scientists use to obtain measurements important for climate studies is an atmospherically emitted radiance interferometer, or AERI. This sophisticated instrument measures the absolute infrared spectral radiance of the sky directly above the instrument. In July, the ACRF Southern Great Plains (SGP) site hosted a new instrument for measuring these spectra, called the Atmospheric [...]

Like many scientific organizations, the ACRF Data Archive stores and distributes atmospheric data from the ACRF sites in Network common data form, or NetCDF. This file format applies names or attributes to the various layers of data for efficient identification and processing. Then, using an interactive web-based tool called NCVweb, users can plot the data [...]
