Grid time series data base

Fundamental properties

  • Quick imports of grids
  • Rapid output of time series
  • Long-term archiving
  • Dynamic access
  • Location accurate evaluation. Tile oriented, not point oriented
  • Concatenation of different grids of diverse grid sizes
  • Input formats: Grib, Grib2, NetCDF, ZAMG, Radolan
  • Multi-parameter grids (e.G. ensemble data)
  • Connection to tstp. Control via Shape. Combination with time series
  • Special transformations: rotated pole, polar stereographic projection
  • Customisable, e.G. polar coordinates, other input formats

A grid time series data base request is made via tstp server. A shape file of polygones (areas, e.g. fractions of catchment areas, field blocks) is passed to the grid. In picture 2 such a polygon is shown. These polygones are blended with tiles. Tiles wich are only partly covered by the shape get a wheight as shown in pictute 3. All filtered tiles inclusive their wheigts get averaged. After that, all tile values for the desired time period are calculated. For data base requests, these values are stored in the Grid-ZR-DB for fast access. Therefore, no grids are stored in the Grid-ZR-DB. Generating grids from a Grid-ZR-DB is not provided.
