It's not SeaDAS, but you could use the standard linux program, bc, like this.cat <<EOF >sample_chl_anomalies.txt0.020.0142.40.260.0890.37EOFfor c in `cat sample_chl_anomalies.txt`; do  echo "l($c)" | bc -l >> log_sample_chl_anomalies.txtdoneOr you could use my favorite, reverse-po...

One more short post script:

When working with Landsat 8 data, I have found that I can often make
a decent radiometric land mask for the scene in question by fiddling
with the contrast of the rhos_865 product from l2gen.

Hi Amanda,The l2gen program does not change the projection of the Landsat 8 scenes duringprocessing.  The output pixels have the same universal transverse Mercatorcoordinates as the corresponding input pixels.  In addition, l2gen stores thelatitudes and longitudes of each pixel in separate...

Hi Mati,

Have you specifically registered to download HICO data?

If so, can you share a specific URL that is not working for you?

If you haven't already, you might consider applying for the biennial ocean opticscourse held at the University of Maine in the summer.  This year's class is nowfilled, but this is probably one of the best introductions around for the field ofsatellite ocean color.  I am not an alum...

Hi Daniele,I assume you are referring to this image.https://oceancolor.gsfc.nasa.gov/feature/AnomalousEquatorialPacificBloom/A2007311222500.TropicalSouthPacificBloom.pngI made it while being paid by U.S. tax payers using a tax-payer-funded data set,so the image is in the public domain and free to be...

Hi Daniele,

Those gaps in coverage are places where no valid pixels were
recorded over the entire compositing period.  The primary cause
of this is persistent cloud cover, but other factors such as sun glint
or heavy aerosol can also sometimes play a role.

Hi Daniele,

You forgot to add the attachment to your last post.

Hi Daniele,I make many of the images in the gallery that you refer to, but there are twofactors that you should be aware of regarding those images.  I, for the most part,choose scenes that are not overly cloudy and that  have relatively high levels ofphytoplankton biomass or other suspende...

Hi Daniele,It would probably be better to start a new topic on the forum fornew questions.Have you considered using imagery from our level-3 browser?The following is a recent example.https://oceancolor.gsfc.nasa.gov/showimages/VIIRS/IMAGES/CHL/L3/2019/041/V20190412019072.L3m_R32_SNPP_CHL_chl_ocx_4km...
