IMIS

Format

This plugin reads data directly from the IMIS network database (Oracle database). It retrieves standard IMIS data as well as ENETZ and ANETZ data.

Units

The units are assumed to be the following:

  • temperatures in celsius
  • relative humidity in %
  • wind speed in m/s
  • precipitations in mm/h
  • radiation in W/m²

Keywords

This plugin uses the following keywords:

  • COORDSYS: input coordinate system (see Coords) specified in the [Input] section
  • COORDPARAM: extra input coordinates parameters (see Coords) specified in the [Input] section
  • COORDSYS: output coordinate system (see Coords) specified in the [Output] section
  • COORDPARAM: extra output coordinates parameters (see Coords) specified in the [Output] section
  • DBNAME: name of the database to use (exemple: sdbo)
  • DBUSER: user name to use when connecting to the database
  • DBPASS: password to use when connecting to the database
  • STATION#: station code for the given number #
  • USEANETZ: use ANETZ stations to provide precipitations for normal IMIS stations. Almost each IMIS station is associated with one or two ANETZ stations and does a weighted average to get what should be its local precipitations if no local precipitation has been found (either nodata or 0).
  • USE_IMIS_PSUM: if set to false (default), all IMIS precipitation will be deleted (since IMIS stations don't have heated rain gauges, their precipitation measurements are not good in winter conditions). If set to true, the precipitation measurements will be accepted from IMIS stations. In this case, it is strongly advised to apply the filter FilterUnheatedPSUM to detect snow melting in the rain gauge.
  • USE_SNOWPACK_PSUM: if set to true, the SNOWPACK simulated Snow Water Equivalent from the database will be used to compute PSUM. Data gaps greater than 3 hours on SWE will lead to unchanged psum while all data that can properly be computed will overwrite psum. (default=false)

It is possible to use both USE_IMIS_PSUM and USE_SNOWPACK_PSUM to create composite PSUM (from SNOWPACK in the snow season and from IMIS otherwise). In such a case, as soon as SNOWPACK SWE > 0, all previous PSUM data will be deleted (ie those potentially coming from IMIS_PSUM). But if there is no SNOWPACK data, the IMIS measurements will be kept.
