The Ocean Productivity Site has stopped updating its data.
We hope to continue operations shortly.

Online Data: CbPM
1080 by 2160 8day HDF files from MODIS R2022
Data
note: (08.21.2024) data updated back to the start of 2021 using the new MODIS.R2022.0.1 reprocessing results
note: data updated 04.21.2022 using the new MODIS.R2022 reprocessing results
production of gsm data was discontinued
now using bbp_giop and chlor_a (instead of bbp_gsm and chl_gsm)
also switching to mld030 (instead of mld125)
note: all data updated 03.05.2018
using the new MODIS r2018 results
note: all data updated 04.19.2017
using new single-source mld data

To get these data,
please click on the file name(s) that you have selected
and save locally on your computer.
The individual hdf files are gzipped
(use gunzip to uncompress)
and the tar files contain gzipped hdf files.
cbpm = net primary production (units of mg C / m**2 / day ) based on the updated cbpm algorithm
yyyy = year
ddd= day of year of the start of each 8day file
hdf = file type
gz = compressed with gzip (uncompress with gunzip)
The hdf files have metadata contained within them, which can be examined, for example, with program "ncdump".
npp is based on the updated cbpm algorithm, using gsm chl and gsm bbp (both modis derived
products),
modis par and k490, as well as nitrocline depth and mld for input;
clouds have been filled in the input data using our own gap-filling software.
