    Description

    This data compilation was made to estimate whole lake metabolic rates based on the O2-free water method. It contains basic quality controlled YSI and PAR data and processed YSI and PAR data. 

    The available processed YSI parameters are: water temperature, conductivity, oxygen concentration. For these parameters extensive quality controll in regard to impossible values and outliers was done.

    Also PAR data is available as intensive quality controlled version, i.e. removal of impossible values and outliers.

    In addition estimated hourly and daily attenuation is provided, as well as salinity

    The data was merged with processed and quality controlled wind measurements standardized to 10 m from sensor placed at 30 cm and 230 cm above water level at encolsure E23 

    The data was further merged with hourly atmospheric pressure data.

    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)
