Question: Sunglint calculation
Replies: 6

Re: Sunglint calculation

Looks like the calculation of alpha in getglint.f is unnecessary with the assumptions made. Yes. The code is capable of supporting wind direction, but it is not used to do so. The windspeed is also assumed to be isotropic (because of the lack of wind direction information), so there are indeed some...

Re: CHLOROPHYLL A UNIT

The variable has a units attribute that you can check to verify the units, but yes, the units for the chlorophyll product are in mg /m3 :D

Re: Updating to SeaDAS 9.0.1

Bruce,

It is just the visualization package. We will be releasing a science software update soon(ish), but the will not be a need to update the SeaDAS to get the OCSSW update

Question: L2gen - cant remove HILT flags MODIS
Replies: 5

Re: L2gen - cant remove HILT flags MODIS

When the HILT flag is set for MODIS, one or more of the bands are saturated. It is often that the 869nm band is saturated, this band is used in the atmospheric correction. Disabling the masking of HILT will not change the fact that the data are saturated and a saturated 869nm band will cause the aer...

Re: Finding and Retrieving PACE OCI Level-1 and Level-2 Granuals For a Specified Region

Bruce, 'Tis true that the venerable browse.pl does not support PACE. However, search.earthdata.nasa.gov does (and will eventually replace browse.pl for all sensors). Spatial and temporal data search is possible with this tool and soon (I hope) we'll have extracted data ordering capability enabled fo...

Question: L2gen processing of VIIRS SNPP is missing some bands
Replies: 4

Re: L2gen processing of VIIRS SNPP is missing some bands

It is not the atmospheric correction option, it is: l2prod=Rrs_vvv "_vvv" tells l2gen to expand the products to the list of visible wavelengths - which to not include the NIR bands. You will need to explicitly define the NIR bands for l2gen to return them. Keep in mind, if you request a ba...

Question: PACE L3M grid
Replies: 1

Re: PACE L3M grid

Toby, I argued for only one resolution (the 4.6km) 8-) PACE is more than just oceans, and some folks from the atmosphere discipline proposed we distribute a 0.1 degree resolution, so we're back to two. The 9.2 km was produced to maintain consistency with SeaWiFS when we started producing the MODIS d...
