  • Radiation Data Quality VAP Now Available for CACTI Field Campaign

    Preparing for the 2018–2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign in Argentina, a technician works on ARM sky radiometers on stand for downwelling radiation. These instruments are a key contributor to the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream…

  • ARM CACTI Radar Data Ascend to New Level of Usability

    Highly characterized data from Argentina achieve data epoch status The second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2) went on its first deployment during the 2018‒2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign in Argentina. The CSAPR2 was one of four ARM radars that operated during CACTI. Photo is by Joseph Hardin, Pacific Northwest…

  • RELAMPAGO-CACTI Workshop All About the Data

    Editor’s note: Adam Varble, principal investigator for the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign, writes about a data workshop held with researchers from the Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO) campaign. The RELAMPAGO-CACTI study region is the birthplace of the world’s largest and tallest thunderstorm…
