REVISED: Large-Scale Forcing Data for AMIE-GAN Updated
Analysis domain for Revelle, with diameters of 300 km. The red star denotes the ship location. Editor’s note (October 17, 2019): Large-scale forcing data developed from a constrained variational analysis approach have been reprocessed and made available for the ARM Madden-Julian Oscillation (MJO) Investigation Experiment on Gan Island (AMIE-Gan) in the Maldives. The data use…

REVISED: New Shallow Cumulus VAP Available
These plots provide data about shallow cumulus events at ARM’s SGP Central Facility in June 2017. The top panel shows days with shallow cumulus events. The bottom panel gives more information for up to four events, including whether the event contained overlying cirrus, was not detected because no low clouds were found, missed the length…

New Radiation Data Quality (QCRAD) VAP Release Available for AWARE Field Campaign
The top plot shows best estimates of global shortwave (GSW) downwelling radiation at McMurdo Station, Antarctica, on January 1, 2016, during the AWARE field campaign. The bottom plot shows quality control (QC) flag values indicating the sources of the best estimates for GSW. The Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP)…

Continuous Large-Scale Forcing Data for Cloud Modeling From Southern Great Plains Extended to October 2018
The seasonal cycle of Southern Great Plains domain-averaged latent heat (LH) and sensible heat (SH) fluxes is shown by using QCECOR-only (QCECOR), BAEBBR-only (BAEBBR), and both QCECOR and BAEBBR data (merged) averaged from 2004 to 2015, and the impact to the derived large-scale vertical velocity (omega). Version 2 of the continuous forcing value-added product uses…

LASSO Data Bundles Released for 2018 Shallow Convection Season
A cross section from a LASSO simulation using the 75-km Multiscale Data Assimilation large-scale forcing on May 23, 2018 (17 UTC), shows vertical velocity (W, colors) with overlaid contours of cloud water content (10−6 kg kg−1), which indicate cloud locations at ARM’s Southern Great Plains atmospheric observatory. The tendency for clouds to be rooted to…

MPLCMASK Evaluation Data Available for MARCUS Campaign
Sample plots from the MARCUS deployment show the log10 (backscatter) and the LDR for a selected range and UTC time for February 18, 2018. An updated version of the Micropulse Lidar Cloud Mask (MPLCMASK) value-added product (VAP) provides cloud boundaries and linear depolarization ratio (LDR) for the Measurements of Aerosols, Radiation, and Clouds over the…

Improved Quality Controlled Eddy Correlation Flux Measurement Data Extended for SGP
Eddy correlation flux measurement (ECOR) systems, like this one at the Southern Great Plains observatory, are installed at ARM’s fixed and mobile observatories. These systems provide key measurements for the QCECOR VAP. Another year of data have been processed for the Quality Controlled Eddy Correlation (QCECOR) value-added product (VAP). This VAP provides improved surface turbulence flux…

New Radiation Data Quality (QCRAD) VAP Release Now Available
A broadband radiometer station at ARM’s Southern Great Plains Central Facility near Lamont, Oklahoma, measures broadband solar (shortwave) and infrared (longwave) radiation. Data from this station have been processed as part of a new release for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. A new level 2 (c2/s2) release for the…
