Hello, I am looking for the old parameter database mentioned in this post from a few years ago:

> Hey everyone, NatCap used to host a really nice parameter database for InVEST models, with literature citations and example biophysical parameter values. Anyone know if that is still available and where I could find it? Thank you!

I’ve looked through the NatCap Data Hub but I cannot find this. To be clear, I am looking for the sheet that compiled parameter values for several models (sediment, nutrient, carbon) along with citations for the sources and tags for country, region, etc.

Do you still host the database somewhere?

Thanks!

Adrian

Hello @adrianvogl , yes! These parameter tables have been very persistent. Although they are not currently linked on the website (that may change in the future), the are still available in the user’s guide repository here: [invest.users-guide/data-sources at main · natcap/invest.users-guide · GitHub](https://github.com/natcap/invest.users-guide/tree/main/data-sources)

For the record, those tables are old enough that some of the parameters in the table no longer correspond with modern versions of the models. And there is no documentation on the units provided in the table values, which is likely to be an issue with at least NDR, as the loading units required by the model changed a while back. So these tables really need to be updated. If you do download either the NDR or SDR spreadsheets, be sure to also get the [methods document](https://github.com/natcap/invest.users-guide/blob/main/data-sources/database_methods_0212%20.docx) that’s in the GitHub repository that James linked to.
