Re: Opening downloaded .nc files

When I tried to use group = "parameter" it gave me the error "OSError: [Errno group not found: parameter] 'parameter'", but I found from a different source that specifying group = "product" helped me access the data. Maybe it had to do with my machine being a Mac, but u...

Re: Obtaining dimensions from .nc4 files

I was able to access the latitude and longitude when I didn't specify the group when opening the .nc4 file. So I did no2obj1 = 'TEMPO_NO2_L3_V03_20240708T151622Z_S007_subsetted.nc4' no2data1 = xr.open_dataset(no2obj1, group = 'product') no2data1 = no2data1['vertical_column_troposphere'].values no2co...

Negative numbers in TEMPO L3 NO2 and HCHO data

I have been working with TEMPO L3 subsetted files for NO2 and HCHO (last downloaded from NASA EarthData Search around 8/4/2024), and used xarray in python to open them and access the data. When I open and plot the data, some of the data is negative (I believe the units are molecules/cm^2, so negativ...

Re: Obtaining dimensions from .nc4 files

I can't see the images you've attached, but when I open the geolocation folder to select variables, the only ones I see are relative_azimuth_angle, solar_zenith_angle solar, and viewing_zenith_angle. I've attached a screenshot of my variables options below. Thus I'm not sure what's wrong with the wa...

Obtaining dimensions from .nc4 files

I have been working with the subsetted .nc4 files for NO2 data from TEMPO, last downloaded from NASA Earthdata on 08/01/2024. I selected the region I wanted data for, but when I download and extract the data the dimensions just show up as arrays of integers from 0 to 68 and 0 to 42 (latitude and lon...

Opening downloaded .nc files

I'm currently (7/30/2024 16:00:00 PST) trying to download both normal and subsetted TEMPO NO2 L3 data from EarthData search, and I'm downloading the files straight from the database. I'm opening the files in python using xarray in VScode in python, and the only variables that come up are weight and ...
