PAR003 Optical disdrometer data at Erasmus MC in Rotterdam

<strong>Description:</strong> In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR003" on the roof of the Erasmus MC in Rotterdam, at a height of approx. 20 meters. This dataset was collected during the campaign RITA2022, which took place in the city of Rotterdam between August and September 2022. The RITA2022 campaign involved many other sensors from TU Delft and partners of the Ruisdael consortium. Some additional data collected before and after the official campaign dates are included as well.<br><strong>Format:</strong> Each NetCDF file covers a full month of observations. The temporal resolution is 1 minute. Data are provided "as is", without any post-processing. The NetCDF files contain all relevant information about all the variables, attributes and units. The global attributes of the NetCDF files contain important information about the type of sensor, logging software, project contributors and history of the dataset.<br><strong>Relevance:</strong> Optical disdrometer data are useful for studying the type, dynamics and microphysics of precipitation from the perspective of a fixed observer on the ground. The data can be used to help calibrate weather radars, improve quantitative precipitation estimates, calculate the absorption/attenuation/propagation of electromagnetic signals through the atmosphere, and quantify important physical quantities such as liquid water content, rain amount, intensity and kinetic energy.
