    Radar reflectivity - data measured with an X-band radar at 213 m height in Cabauw

    This dataset contains X-band (9.475 GHz) weather radar measurements from the TU Delft IRCTR drizzle radar IDRA. It includes plan-position indicators (PPI) of co-polarised reflectivity measurements at horizontal polarisation. IDRA is mounted at the top of the Cabauw tower and is scanning horizontally at a fixed low elevation angle, covering a radius of 15 km (30 m range resolution) or 1.5 km (3 m r…

    Soilmoisture - daily values taken with a TDR array at midnight local time at Cabauw

    Volumetric soil moisture contents have been measured daily between 6 november 2003 and 19 August 2010 with a TDR set-up developed by Heimovaara and Bouten consisting of six arrays of six sensors between 5 and 73 cm below the soil surface. The six arrays were positioned on the perimeter of a circle with a diameter of 9 m with equal distances. The TDR was calibrated by taking 6 undisturbed soil samp…

    Surfacewater - hourly surface water discharges in catchment at Cabauw

    Discharge has been measured at three locations. At these locations, measurement weirs have been installed in May 2007 to estimate discharges accurately. A V-notch weir is used to measure the inflow of surface water into the catchment near the Wielse Kade (Qin). Trapezoidal Rossum weirs have been installed to measure outflow (Qout1 and Qout2), of which the stage-discharge relations have been obtain…
