Dear Ocean Color Users, The Ocean Color web services will be migrating all services that require user authentication to the NASA’s Earthdata Login (User Registration Service, URS,https://urs.earthdata.nasa.gov/).   This includes the Ocean Color Forum, near real-time data subscriptions, data ordering...

The Ocean Biology Processing Group generates a near real-time rolling 3 day Level 3 product. This product is intended to serve as a "quick look" providing more spatial coverage than is available in the daily Level 3 product. Unlike the daily product, these rolling 3 day products are not re...

MODIS Aqua Ocean Color reprocessing is now in progress, with completion anticipated late June.  Old HDF4 product will continue to be produced until at least 6 July.

Christophe,Almost.  The code released with SeaDAS v7.2 can process HICO with the full spectral resolution.  The hicohs data tree needs to be put in place of the hico data tree for this to work.It's still a work in progress, so no guarantees on the products it produces.  Little thi...

Dear OBPG User,There is a planned NASA-wide network outage this Sunday, April 26.  Network connectivity to our servers will be affected between the hours of noon and midnight Central Daylight Time (26 April 1700 GMT through 27 April 0500 GMT).An outage of 1-4 hours is planned between 1700 GMT to 230...

To quote from one of my favorite movies..."We have top men working on it right now".However, I cannot give an estimate as to when it will be finalized, but will say with confidence, not before the Spring....the conspiracy theorists  out there will notice I didn't put a year on tha...

Processing with the "null" landmask, or with the maskland=0 option set will still result in atmospheric correction failures over land.  The l2gen program is designed to retrieve over water.  All that using the null landmask does is force l2gen to process all pixels regardless ofw...

If your BEAM installation has the latest version of the seadas_reader module, then yes. Otherwise, no.

You can set maskland=0 or to be really sure land=$OCDATAROOT/common/landmask_null.dat.
Keep in mind we have NOT vicariously calibrated HICO, so while you may get a retrieval, the results may not be valid.

As Jasmine pointed out, l2gen currently only supports a "multi-spectral" HICO (16 bands matching MERIS wavelengths).   We've also not vicariously calibrated HICO.It is possible that the data have been flagged as cloud or another mask condition that would prevent atmospheric c...
