    Period length
    2 years 11 months 30 days
    Sampling interval
    Irregular Interval
    Note on interval
    Time-steps vary from hourly to monthly data. Monthly data are primarily isotope datasets (soil/groundwater)
    Description

    Meteorological data were measured at Hasenfelde - reported here as hourly data

     - Wind speed, air temperature, air pressure, humidity, precipitation, radiation

     

    Precipitation isotopes 

     - Daily samples at Hasenfelde

     - Weekly samples at various locations (stream locations) in the catchment

     

    Throughfall and throughfall isotopes

     - Taken at soil moisture measurement sites - weekly samples

     

    Discharge

     - Daily measurements reported at Demnitz Mill (and rating curve) and Berkenbruck

     

    Groundwater Level at 5 locations

     - Elevation of surface, below ground, bottom of well, and time-series of water level (translated to m a.s.l.)

     

    Groundwater isotopes at 5 locations

     - Roughly monthly samples at various locations in the catchment, spread through the center and south reaches of catchment

     

    Soil Moisture

     - Measured at 2 locations (Forest A and Grass A) at 3 depths 20,60, and 100cm with soil temperature at each depth

     

    Soil Isotopes

     - Measured through bulk soil sampling at locations (Forest A and Grass A) at multiple depths

     - Depth ranges indicate bulk soil samples taken between specified depths

     

    Sapflow

     - Measured average sapflow of forest stand at Forest A

    Parsing data File

    Estimated Time:

    Why does it take so much time?

    While parsing a file, the database has to perform various tasks, some of them needs a lot of CPU and memory for larger files.

    • preprocessing: means automatic detection of headlines, table body, format values or csv-separators
    • copying: means read the file cell by cell and copy all elements to the database. During this format settings can be calculated (for example iso-time)
    • analyzing: check out for different data types (can be time, numeric or text)
