Re: Subsetting MUR-JPL-L4-GLOB-v4.1 data?

Hi!

Thanks for the response! I too managed to reach the same conclusion as you did after some testing, it works alright and is relatively fast. I just thought there was a more elegant solution.

Thanks again! Cheers!

Subsetting MUR-JPL-L4-GLOB-v4.1 data?

Hi! I'm trying to subset data from the MUR-JPL-L4-GLOB-v4.1 set ( https://podaac.jpl.nasa.gov/dataset/MUR-JPL-L4-GLOB-v4.1?ids=&values=# ). However, since the migration to cloud-based storage, I've found it increasingly difficult to do so. Are there any tips or tutorials on how to actually do th...

Re: HawkEye L2 coordinates - where are they stored?

Hi, another question, kind of related. The timestamp in the filename is UTC, right? Thanks!

HawkEye L2 coordinates - where are they stored?

Hi all!

I'm thinkering a bit with the HawkEye L2 data, but I seem not to be able to find the coordinates.
I've unpacked the .nc file using

Code: Select all

nc = xarray.open_dataset(file, group = "geophysical_data")
Could you please point me to the storage location of the coordinates? Thank you!

Question: Data level distinction?

Re: Data level distinction?

Combining the two sources it is implicitly implied that L is the only level 1 physical variable, everything else is level 2. Thanks!

As for suggestions, I reckon some tacit examples of data levels in the documentation would be of great use.
Thank you once again! :D

Re: Data level distinction?

Hi!
Thanks for the reply. I'm aware of the documentatiton, but the term "geophysical" is still too vague to me and doesn't really help me place radiance and/or reflectance into level 1 or 2...

Data level distinction?

Hi! I'm having some trouble grasping the distinction between data levels and actual physical interpretation of data. Say we are talking about chlorophyll concentration: level 1 would include both radiance L (power of the light radiation at specific wavelength per unit solid angle per unit area) and ...

Question: What exaclty are Level 0 and Level 1 data?

Re: What exaclty are Level 0 and Level 1 data?

Thanks for the advice!

So L1 data is radiance, but the L0 is still a bit vague to me, at least physically.

"Production Data Set (PDS) is the raw instrument package" would that be the measured product of photovoltaic/photoelectirc effect?

Thank you!
