PERiLS_2023: Portable In Situ Precipitation Stations (PIPS) Data


Data from the Purdue University Portable In Situ Precipitation Stations (PIPS) that were deployed at locations around the southeastern United States for three PERiLS 2023 deployments. The PERiLS deployments were on 3, 24 and 31 March and 5 April 2023. The PIPS are a set of 6 instrumented probes equipped with conventional surface meteorological instrumentation as well as Parsivel 2 laser disdrometers. Their mission in PERiLS was to collect drop size distribution and other surface observations to characterize the surface microphysical and thermodynamic variability in time and space as the quasi linear convective system (QLCS) moves over the array. During PERiLS 2023, the PIPS were deployed in IOP’s 2-5 in QLCS’s and supercells.
