  • Large-Scale Forcing Data Released for SAIL Campaign

    Continuous large-scale forcing data are now available for the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign. The Atmospheric Radiation Measurement (ARM) user facility conducted the SAIL campaign in high-altitude complex terrain near Crested Butte, Colorado, from September 2021 to mid-June 2023. Scientists can use this value-added product (VAP), known as VARANAL, to drive single-column…

  • Large-Scale Forcing Data Released for TRACER Campaign

    Continuous large-scale forcing data are now available for the TRacking Aerosol Convection interactions ExpeRiment (TRACER), conducted by the Atmospheric Radiation Measurement (ARM) user facility from October 2021 through September 2022 in the Houston, Texas, area. The derived forcing data are based on a constrained variational analysis approach (Zhang and Lin 1997; Zhang et al. 2001).…

  • 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…

  • Large-Scale Forcing Data Released for Macquarie Island Campaign

    The map shows the variational analysis domain (enclosed by the red circle) for the Macquarie Island Cloud and Radiation Experiment (MICRE). The domain is centered at 158.9oE, 54.5oS. The ARM site on Macquarie Island is located at the center of the domain. Continuous large-scale forcing data are now available for the Macquarie Island Cloud and…

  • Large-Scale Forcing Data Released for COMBLE Campaign

    The map shows the variational analysis domain (enclosed by the red circle) for the Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE). The domain is centered at 14.9oE, 70.6oN. The first ARM Mobile Facility (AMF1), sited near Andenes, Norway, is located at the edge of the domain. Continuous large-scale forcing data are now available…

  • Large-Scale Forcing Data Released for West Antarctic Campaign

    The map shows the variational analysis domain (enclosed by the red circle in the left bottom corner) for the ARM West Antarctic Radiation Experiment (AWARE). The domain is centered at 77oS, 168.25oE, near McMurdo Station on Ross Island. Four months of continuous large-scale forcing data are now available for the ARM Mobile Facility deployment at…

  • Updated Southern Great Plains Continuous Large-Scale Forcing Data Released

    The plots show the time series of the derived large-scale vertical velocity (Omega) in a previous VARANAL version 2 release for July 2018 (top) and in a new release with a bug fixed (middle), and the difference between the two releases (bottom). The bug only affects the time periods after 18 UTC July 21, when…

  • 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…

  • Continuous Large-Scale Forcing Data Now Available for Cloud Modeling From Southern Great Plains

    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 2004-2015, and the impact to the derived large-scale vertical velocity (omega).
