In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR002" at the remote sensing site in Cabauw. Note that "PAR002" is co-located with another identical disdrometer called "PAR001". This co-location can be used to cross-check data, perform quality control and/or assess measurement uncertainty due to sensor calibration, random sampling effects and environmental effects such as wind speed/direction which are known to substantially affect the accuracy of optical disdrometers.  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR003" at the Green Village site in Delft. Note that the Green Village site is different from the other Ruisdael sites. Its primary purpose is to allow researchers to test sensors, perform calibration and develop new hardware/software solutions. The Green Village also serves as a temporary home basis for all the mobile sensors used during field campaigns. Due to the special nature of this site, data quality, reliability and availability may be lower than at other locations. There are also some nearby obstacles such as trees and fences which may affect the accuracy of the precipitation measurements depending on local wind patterns.  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR004" in Westmaas, The Netherlands. Westmaas is a village in the Dutch province of South Holland located approximately 15 km south of the city centre of Rotterdam, south of the old Meuse. The same site also features a micro-rain radar "MRR003_Westmaas" (since June 2022) and a Davis weather station "Davis003_Westmaas" (since May 2023). All sensors are placed on top of an air quality monitoring container belonging to TNO, at a height of approx. 4 meters. The container is located approximately 1.5 km to the West of the village of Westmaas, in a predominantly flat and rural area.  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR005" in De Zweth, The Netherlands. Situated approximately 7 km to the North West of Rotterdam, and 4 km South East of Delft campus, Zweth is a small town along the Schie river, at the intersection of the historical areas of Delfland and Schieland. The same site also features a micro-rain radar "MRR004_DeZweth" (since February 2022), replaced by "MRR006_DeZweth" (since August 2022) and a Davis weather station "Davis003_DeZweth" (since May 2023). All sensors are placed on top of an air quality monitoring container belonging to TNO, at a height of approx. 4 meters.  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR006" in Slufter, The Netherlands. Located in the Maasvlakte Rotterdam, The Slufter is a large-scale storage site for contaminated sludge in the southwestern part of the Rotterdam Maasvlakte, approximately 31 km West of the city center of Rotterdam. Along the ring dike of the Slufter, several wind turbines belong to the Windpark Slufterdam are providing electricity for the region. The same site also features a micro-rain radar "MRR005_Slufter" (since March 2022). All sensors are placed on top of an air quality monitoring container belonging to TNO, at a height of approx. 4 meters. The rough climate conditions near the coast of the North Sea, with high winds, salt, and sand creates a very challenging environment for long-term weather observations. Consequently, data availability tends to be lower than at other sites, due to frequent maintenance and technical issues.  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR007" at a height of 180 meters in the meteorological tower of Cabauw. This highly unusual location for a precipitation sensor was specifically chosen to study the effect of wind, turbulence and shielding on raindrop size distributions, as well as to quantify the vertical variability of rain near the surface. Two other disdrometers "PAR001_Cabauw" and "PAR002_Cabauw" located on the ground, approximately 200 meters away can be used as a reference to assess biases and measurement uncertainty. The site also features a vertically profiling micro-rain radar named "MRR002_Cabauw".  +
In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR009" at a height of 3 meters at the Lutjewad atmospheric measurement station on the northern coast of the Netherlands, approximately 30 km northeast from the city of Groningen. The rural landscape to the south consists mainly of pasture and cropland with patches of forested land with livestock dominated by dairy cows and sheep. Set up directly behind the Wadden Sea dike, the site features a 60 meter tall sampling tower, a 10 meter platform, a laboratory building, and an aerosol laboratory container. The station monitors greenhouse gases and trace gas species, sampling aerosol number, size, and composition at different altitudes. Lutjewad is part of the European research infrastructure ICOS, providing continuous greenhouse gas concentrations. The coastal location means that the site samples relatively clean marine background air in conditions of northerly winds and more polluted air masses during conditions of south-easterly and south-westerly winds.  +
Description: In-situ measurements of temperature, pressure, relative humidity, rain, solar irradiance and wind (at a temporal resolution of 1 minute) by a Davis Vantage Pro2 weather station named "Davis-001" on the roof of the Erasmus MC building in Rotterdam, The Netherlands, at a height of approx. 112 meters. This station is part of the Rotterdam Atmospheric Measurement Network (RAMN), funded with the help of TU Delft strategic funds, in collaboration with the Ruisdael Observatory. Note: The station was installed on June 13, 2023 but suffered major technical issues during the first two months. It was then damaged during a storm on July 14, 2023 and had to be brought back to TU Delft. As a result, only a few days of observation are available for now.  +
