Help on accessing numerical data sheets on Net Primary Production

Is there a way to access and download numerical data on global NPP? I am an undergrad and I am trying to find out if there is a relationship between NPP and climate change.

Hello,

Are you trying to find terrestrial NPP, oceanic, or total?

I would like to find the total NPP, but if it's not too much to ask both the oceanic and terrestrial would be great.

The total would be great, but I would also like to use both.

Hello,

You can obtain terrestrial NPP from MODIS via the LP DAAC.

https://earthdata.nasa.gov/search?q=npp+mod17a3

Ocean NPP based on SeaWiFS data is available here
http://sites.science.oregonstate.edu/oc ... ductivity/ This can probably be used for basic estimates even though the time period is 1997-2009.

For more recent data, look under Custom Products
http://sites.science.oregonstate.edu/oc ... custom.php

This page has a few annual Land/Ocean merged NPP products.

I hope those will be useful to you.
