There is no easy route to maximizing the useful information from a series of images.  It is often helpful to compare results using different methods and then go back to the level-2 data to understand what is causing the differences.  It is often helpful to use a "robust measure of cen...

Those sensors are far from ideal for intertidal locations.   Two big issues for these sensors are:1. land is highly reflective compared to water.   Sensor responds drops off away from the pixel center, with a bell-shaped response.  A bit of land near the edge of the "be...

For me, Module Manager takes a very long time to scan.  The progress bar often stalls, but usually starts to move again.  If it realy fails, you should get an error popup.Since you know you want the seadas-reader-1.7.2 module, it is faster to update manually.  Some hints are given Mod...

Updating the LUT's is the last step in the installation.  At my site the update LUT's steps often fail, but running update_luts.py from the command line generally works (but may take a couple attempts).  To use the command line script you will need to add the lines to your ~/.bashr...

You aren't doing anything WRONG, just pushing the limits of historical conventions (which didn't allow "." in a username due to legacy usage: "chown user.group ..."; current usage has changed to "chown user:group ..."). Using an ocssw.test user account on macOS ...

In my lab we run into changes in raw storage format and scaling with netcdf-cf data sets from non-NASA sources.  In all the cases that were brought to my attention, explicit hard coding conversions and rescaling could be removed using current NetCDF libraries, resulting simpler and more robust ...

I'm sure someone at NASA can explain the difference between the vxx.xxx.xx.xx and vxx.xxx.xx.xxc files, but since mismatches like the one you have are a problem at my site, I'll pass on what I have learned.The NetCDF metadata for V2017124173600.GEO-M_SNPP.nc has:source = "V2017124173600...

Adding an ocssw user will require an admin, but only for a few minutes unless your site's policies require an extensive paperwork exercise for such accounts.

For every forum post like yours there are many other users who just give up and rely on the standard NASA products and most problems encountered by forum users show up sooner of later in our lab. I suggest you set up a new "ocssw" account andt install using only the command-line (the defau...
