  • Hazard maps published by the KNMI. The last version (v4) has been published on June 15, 2017. Previous versions were originally published in June 2016 (v2), October 2015 (v1) and December 2013 (v0). The hazard map shows surface peak ground acceleration (PGA, period T = 0.01 s) in the unit of [g] (9.82 m/s^2). The hazard map is calculated for the province of Groningen in the northern part of the Netherlands. The technical reports explain the specifications of the different versions of the hazard maps: http://www.knmi.nl/kennis-en-datacentrum/publicatie/probabilistic-seismic-hazard-analysis-for-induced-earthquakes-in-groningen-2013, http://www.knmi.nl/kennis-en-datacentrum/publicatie/probabilistic-seismic-hazard-analysis-for-induced-earthquakes-in-groningen-update-2015, http://www.knmi.nl/kennis-en-datacentrum/publicatie/probabilistic-seismic-hazard-analysis-for-induced-earthquakes-in-groningen-update-june-2016, http://cdn.knmi.nl/system/readmore_links/files/000/000/408/original/20170615_Technisch_rapport_hazardkaart_Groningen_2017.pdf Seismic hazard map 2017 (v4) which provides the spectral accelerations for specific locations and return-periods: http://rdsa.knmi.nl/hazard/

  • Historic gridded files of daily precipitation sum in the Netherlands from 1910-2015 based on observations of the voluntary network. The time interval is 08:00-08:00 UT. The number of observations varies: 1910-1951 (102), 1951-2015 (260). Transformed to KNMI14 climate scenario 2085 GL.

  • Archive of volume data of all polarimetric radar variables, including those related to quality for the radar in Herwijnen. Time interval is 5 minutes. Data have been archived in one .tar file per day.

  • In the framework of a long-term joint co-operation between Japan and KNMI aimed at climate reconstruction of Japan in its pre-instrumental era, we now explored the availability of the mostly visual weather data in the daily Diary of the Chief of the Dutch trading post on the island Dejima near Nagasaki. A Pilot project extracted the Januaries of the years 1700-1860; the Follow-up project extracted all months during the period 1817-1823, the term of office of the Chief Jan Cock Blomhoff. Together with the subsequently extracted Von Siebold data 1825-1828 (a supplementary project), the Cock Blomhoff series provides a detailed picture of the Kyushu daily weather in the early 19th century. With this report all data are made systematically accessible and available for further analysis.

  • Historic gridded files of daily Makkink evaporation for 1910-2015 in the Netherlands. Calculated from sunshine duration (1951-1981) and radiation (1981-2015). The number of observations varies: 1910-1981 (5), 1981-2015 (35). Transformed to KNMI14 climate scenario 2085 GL.

  • 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).
