Re: Question about using wget on for Aqua and Merra2

To answer the question about needing (or not) to pass username/password to wget for the SST data download...you do need to do so. Did you look at the file you downloaded without the credentials? What I'm pretty certain you will find is that it is NOT a netCDF file, but rather an HTML file that is th...

Re: modis_GEO -- Percent valid data (46.00) is less than threshold (95.00)

It's not you, or the code. There is some bad orbit data from 1/31. If we get updated att/eph data that corrects the problem, the data will be reprocessed (you'd need to pull the updated files, but I do not know when or even if they will be available). If you look at https://oceandata.sci.gsfc.nasa.g...

Question: mapgen script with MODIS L2
Replies: 3

Re: mapgen script with MODIS L2

The binner cannont bin the flags because they are a bitwise value that cannot be expressed as a floating point value. The binner uses the l2_flags to exclude data during the binning process - which is what the options you defined in the graph were doing for the band maths step. The flaguse parameter...

Question: Oceandata missing SEAICE_NSIDC_24h.hdf ancillaries for 2023, except DOY 001

Re: Oceandata missing SEAICE_NSIDC_24h.hdf ancillaries for 2023, except DOY 001

The NSIDC-based SEAICE files have been deprecated and are no longer produced. We now use the sea ice fraction field in the CMC SST file to set the flag. The l2gen icefile option accepts this file.

Question: l1bgen_modisa issue
Replies: 2

Re: l1bgen_modisa issue

If you are running l1bgen_modisa directly, you'd need to populate the required environment variables and create the appropriate PCF file. It's quite tedious :D This is why there is a script called modis_L1B.

try:

Code: Select all

$ modis_L1B A2012039091000.L1A_LAC

Question: Difference at 4 decimals of geolocation files
Replies: 3

Re: Difference at 4 decimals of geolocation files

The geolocation product produced by the OBPG is used to support processing through the l2gen program. l2gen performs an internal terrain correction, so we disable terrain correction in the generation of the geolocation files. This is the reason for the differences you are seeing. For the ocean at me...

Question: Level-3 binned data on ERRDAP

Re: Level-3 binned data on ERRDAP

I can pretty much guarantee that ERRDAP does not support our binned format. It is a rather peculiar one, great for storing sparse data and combining with other similarly stored data, but not so much for ease of reading. If you want your data to be supported by an ERRDAP server, it will likely need t...

Re: Level 2 SubscriptionS

We have identified the root cause of this issue. On January 4th, a bug in our subscription manager was identified and corrected. This bug allowed expired subscriptions to have data staged for them if another, non-expired subscription would have those data staged (this only affected non-extracted sub...

Re: Some missing VIIRS-SNPP L3m data day directories

Vardis, SNPP-VIIRS was in safehold from sometime mid-day the 26th of July through mid-day the 10th of August. No data was collected, so no directories created for those days. Some longer temporal data (e.g. 8D, R32, etc.) do exist, and directories for the first day those periods exist. For example, ...

Re: SeaDAS-MOD04

I'll reiterate that it is not a bug in SeaDAS. The HDF file is incorrectly written. Even the HDF4 user guide states the assumption that the fillValue should be of the same type as the data set: "SDgetfillvalue reads the fill value which has been set for the data set specified by the parameter s...
