Global categorial land cover type per land grid cell from 1970 to 2100. Cells may contain built-up area or water. The data is licensed under CC-BY. The IMAGE-team would appreciate to be involved in projects using the data. SSP scenarios are documented in: Energy, land-use and greenhouse gas emissions trajectories under a green growth paradigm, https://doi.org/10.1016/j.gloenvcha.2016.05.008
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 obtained by laboratory calibration. The uncertainty associated with the discharge measurement can be considerable in some cases.
This data set contains output from the model runs that were used to produce the Dutch Offshore Wind Atlas (DOWA), but for the full domain, on model levels and for more parameters. DOWA provides a validated wind climatology based on 10 years (2008-2017) of model data: weather model HARMONIE-AROME is nested in re-analyses ERA5. More information on the website: www.dutchoffshorewindatlas.nl. Note: the proj4 string in the NetCDF file is incorrect. It should be: +proj=lcc +lat_1=52.500000 +lat_2=52.500000 +lat_0=52.500000 +lon_0=.000000 +k_0=1.0 +x_0=649536.512574 +y_0=1032883.739533 +a=6371220.000000 +b=6371220.000000
Climatological radar rainfall dataset of 1 hour precipitation depths at a 1 km grid, which have been adjusted employing validated and complete rain gauge data from both KNMI rain gauge networks. This dataset is updated once a month providing data up to a few months ago.
Historic gridded files of daily Makkink evaporation for 1910-1980 in the Netherlands. Calculated from sunshine duration measured on 5 weather stations.
Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic rain gauges. Time interval is 5 minutes. See data set nl_rdr_data_rtcor_5m_tar/1.0 for an archive that goes back to 2018. Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.
Rain gauge data from water company Waternet, after quality control by KNMI. Raw data originating from a self-maintained network of rain gauges. Delivery of data is every 1-5 minutes.
Monthly mean ozone fields of the MSR. The MSR dataset results from a 30-year data assimilation run with 14 corrected satellite datasets as input, and is available on a grid of 1× 1 1/2° for the time period (1978-2008). The fourteen total ozone satellite datasets are from the instruments TOMS (on the satellites Nimbus-7 and Earth Probe), SBUV (Nimbus-7, NOAA-9, NOAA-11 and NOAA-16), GOME (ERS-2), SCIAMACHY (Envisat), OMI (EOS-Aura), and GOME-2 (Metop-A).
The 30 year average maximum cumulative precipitation deficit per year. By station of the KNMI rain gauge network..
Daily files of wind profiles (10 minute average values) between 11 and 300m altitude, measured by the ZephIR 300M wind lidar (ZX firmware), obtained during a measurement campaign by KNMI at the Cabauw site from February 2020 to June 2020. Related datasets are <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zx973-1s-1">windlidar_cabauw_zephir300M_zx973_1s</a> (with the raw data instead of the 10-minute averaged output), and <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zp738-10min-1">windlidar_cabauw_zephir300M_zp738_10min</a> and <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zp738-1s-1">windlidar_cabauw_zephir300M_zp738_1s</a>, which are wind lidar dataset that were taken with an older firmware (ZP) for the full period of the campaign (Feb. 2018-June 2020).
