Model calibration

I am going to use InVEST terrestrial model for carbon sequestration and storage, water yield and nutrient and sediment retention services for an agricultural watershed. So, here I need some information about the models calibration. Any one who can give general information?

    Hi Ali, 

    You can find general information on model application (including calibration and validation) on the InVEST page online: http://www.naturalcapitalproject.org/invest/
    (Scroll down to see the key references for each model).

    Note that for carbon sequestration there's rarely a calibration per se, given the nature of the model (using direct estimates of C stocks). 

    Best,

    Thank you Perrine

    Is 10 years of data from gauging stations enough for calibration and validation of sediment and nutrient retention models?

    Thanks,

    Hi Ali -

    Yes, 10 years is great. A few things that are important as well:

    - There aren't big gaps of missing data..
    - The 10 years of gauge data overlaps the year that the land cover map is from.
    - Check the units on your gauge data, you might need to do a conversion to compare with modeled output.
