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…
