Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
Yes, a test tag with this fix is being prepped and should be available sometime next week. It will take a little longer to get into a release tag, but as SeaDAS is planning another release in October, it shouldn't be too long of a wait
Yep, that was discovered recently by Alex as well and will be corrected in an upcoming release. The wee bit o'code whoopsie that caused the woe was introduced in August 2024 (in the source code),which jives with Fred's report that the slowness began with V2025.1.
You can use Earthdata Search to identify and retrieve the data or your region of interest. The following link will take you to the OB.DAAC portal and display the MODIS L2 collections: https://search.earthdata.nasa.gov/search?portal=obdaac&fi=MODIS&fl=2%2B-%2BGeophys.%2BVariables%252C%2BSenso...
The l3bin code is some old code and sets up a number of static arrays with what is normally enough space to do its work...and as such it has a hard-coded file limit of 256. Line 26 of l3bin.cpp : #define MAXNFILES 256 I suppose it could be recompiled setting that #define to 512...it should work... (...
Masud, Unfortunately, the l2gen code has a hard limit of 720nm for Rrs output. It has to do with the way the atmospheric correction process works. We have been mulling over the possibility of expanding the output for PACE-OCI, since it does have bands longer than 720nm that are not used in the aeros...
Fundamentally, the current FLH algorithm is the same for MODIS and OCI. OCI just has more bands for deriving the baseline from which the line height is computed. A more sophisticated approach that takes advantage of the high spectral sampling of OCI in the chlorophyll a fluorescence region is planne...
It is normal and intended for MODIS and has been the case since before Terra launched in 1999. Though not how I would have written the code :D , the files need to be writeable. It is only metadata that is modified, not the DNs, so mostly harmless. Different code is used for VIIRS - one that doesn't ...
Clouds, glint and dust. These are challenging regions during those months and such factor as those I listed affect all ocean color products (from all missions, not just PACE).
The bands in the spectral region at the overlap between the two spectrographs in the PACE OCI instrument are not included in the v3.0 L2 products. In the v3.0 release notes, it states: Data in the transition region between the red and blue focal planes, between 590 and 610nm, often shows significant...
