ARM Best Estimate Data Produced for TRACER Campaign
ARMBEATM relative humidity (top) and surface precipitation (bottom) are shown for the first 120 days of 2022 during the TRacking Aerosol Convection interactions Experiment (TRACER). The Atmospheric Radiation Measurement (ARM) user facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the evaluation of global climate models. Two ARMBE data…

Radiative Flux Analysis Data Released for TRACER Campaign
This plot shows irradiance and albedo—surface reflectivity—from the RADFLUXANAL value-added product at the main site of the TRacking Aerosol Convection interactions ExpeRiment (TRACER) from June 20 to 21, 2022. The Radiative Flux Analysis value-added product (RADFLUXANAL VAP) is now available for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER) near Houston, Texas. RADFLUXANAL calculates clear-sky irradiance…

Radiosonde Parameters Calculation VAP Available
This skew-T plot shows the pressure and temperature recorded by an ARM radiosonde launched during the TRacking Aerosol Convection interactions ExpeRiment (TRACER) on June 1, 2022, in La Porte, Texas. Red, blue, and green dots indicate different radiosonde parameters. A new value-added product (VAP) for calculating radiosonde parameters within convective cloud environments is now available…

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,…

Large-Scale Forcing Data Released for CACTI Campaign
The map shows the variational analysis domain (enclosed by the red circle) for the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign. The domain is centered at 64.1oW, 32oS. The first ARM Mobile Facility (AMF1) at Córdoba, Argentina, is located near the southwestern corner of the variational analysis domain. Continuous large-scale forcing data are…

ARM Rolls Out New Products for Determining Boundary-Layer Height
Plots from top to bottom show micropulse lidar (MPL) backscatter; ceilometer (CEIL) backscatter; Doppler lidar (DL) vertical air motion variance; and estimates of planetary boundary-layer height (PBLHT) derived from MPL, CEIL, DL, and sonde measurements at ARM’s Southern Great Plains Central Facility on June 28, 2017. The structure and depth of the planetary boundary layer…

New Precipitation Product Released for TRACER Campaign
This laser disdrometer operated in Guy, Texas, during the TRacking Aerosol Convection interactions ExpeRiment (TRACER). Laser disdrometers measure drop size spectra and fall velocity of hydrometeors. A new precipitation value-added product (VAP) is now available for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER) near Houston, Texas. The Laser Disdrometer Quantities (LDQUANTS) VAP provides quality-controlled…
