Hi Tommy,
Yes, that is a good solution. Thank you for the support!
Best,

Hi Tommy, Thanks for the response. Is there a way to know which L1B source file was used to create the L2 scenes? For example, when looking through the directory for the corresponding L1B scene to "S3A_OLCI_EFRNT.20210405T144930.L2.OC.nc", there were no L1B scenes with a matching date and ...

Hello, I have a question about the L1 source files for OB.DAAC's OLCI S3A/S3B Ocean Color products. I am working with a custom script for l2gen. The OCSSW parts of this script currently works with MODIS-A/T by retrieving names of MODIS OB.DAAC L2 OC scenes (query with earthData), and then uses the t...

I realized that this question was previously asked in this forum: https://forum.earthdata.nasa.gov/viewtopic.php?t=5552. The band wavelength is accessed in group sensor_band_parameters. I have difficulty accessing this group through python but can access it through SeaDas. Following up on that forum...

Hello, I have been following Ocean Color's Jupyter notebook tutorial on file structure at L2 processing levels for OCI "PACE_OCI_L2_AOP_NRT" https://oceancolor.gsfc.nasa.gov/resources/docs/tutorials/notebooks/oci-file-structure/ I am able to successfully plot different rrs bands with the c...

Hi m11keluis, thanks for reaching out. Image IDs: - 'EMIT_L2A_RFL_001_20230603T172005_2315412_008.nc', - 'EMIT_L2A_RFL_001_20230607T154124_2315810_001.nc', - 'EMIT_L2A_RFL_001_20230814T192838_2322613_005.nc', - 'EMIT_L2A_RFL_001_20230818T175401_2323012_005.nc', - 'EMIT_L2A_RFL_001_20230822T161909_23...

Hello, I am working with L2A EMIT data from LP.DAAC (EMITL2ARFL). I was wondering if there is a way to calculate remote sensing reflectance (rrs) from the surface reflectance in this product? I did a simplified conversion (rrs = surface reflectance / pi) and got values that were still quite high (se...

Hello, I noticed in variables for 'add_offset: 0.05' and 'scale_factor: 2.0E-6' in the Rrs Band_attributes for S3A/S3B EFR Ocean Color (OC) product (OLCIS3B_L2_EFR_OC) from OB.DAAC. Are these automatically applied to the .nc file, or do I need to scale and add the factor to the rrs measurements in t...

Hi Sean, Thanks so much! It works now. I have one last question - is there a way to use earthdata to access the .nc VIIRS collection that is on the oceancolor.gsfc.nasa.gov portal? All of the VIIRS collections I see on Earthdata (i.e. VNP09GA) are in .h5 format and not geolocated/scaled. The .nc for...

Hi Sean, Thanks! I saw that VIIRS data on the Earthdata portal is .h5, but on the oceancolor.gsfc portal it is .nc format. I prefer .nc, so I am going to use the ocean color site instead. I am trying to use the obdaac_download script you mentioned to download all viirs/modis,etc. data over a boundin...
