Improved Broadband Radiation Data Available from Multiple ARM Sites
ARM radiometers operate near Lamont, Oklahoma. ARM file photo. The Atmospheric Radiation Measurement (ARM) User Facility processes yearly data from the Data Quality Assessment for ARM Radiation Data (QCRAD) product—the recommended ARM datastream for broadband surface irradiance measurements—to produce level 2 (c2) files. These files undergo additional processing to improve the data. New QCRAD c2-level…

New Data Product Determines Thermodynamic Phase of Cloud Hydrometeors
Thermodynamic cloud phase identification is important to understand many cloud processes such as ice particle production, precipitation formation, and cloud life-cycle evolution, and it is essential to improve our understanding of cloud radiative properties and the atmospheric radiative budget. Because ice particles and liquid droplets have distinct sizes, shapes, fall velocities, and refractive indexes, clouds…

New Broadband Irradiance Data Produced for 2 ARM Sites
This collection of radiometers at Oliktok Point, Alaska, provided continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for downwelling components. ARM stopped collecting data at Oliktok Point in June 2021 after almost eight years. New c2-level data are available from the Data Quality Assessment for ARM Radiation Data (QCRAD) product at Oliktok Point,…
