Re: Geo2Grid v 1.0.1 Sunz and Rayleigh Correction
Yeah, I guess I changed it way back when I used the previous version. I think it works fine now. Last question, if I used the "--dtype float32 --no-enhance", the wrong standard name shouldn't affect the process right?

Re: Geo2Grid v 1.0.1 Sunz and Rayleigh Correction
Follow up this is what's in the ahi yaml file in enhancement which I did not change. enhancements: true_color_crefl: sensor: ahi standard_name: true_color operations: - name: crefl_scaling method: !!python/name:satpy.enhancements.crefl_scaling kwargs: # Polar2Grid's scaling: "Preferred". i...

Re: Geo2Grid v 1.0.1 Sunz and Rayleigh Correction
I only change the content of ahi yaml file in the composites folder to this and did not change the others. I don't think I changed anything about the enhancments. Can I used commands to directly implement the needed stretch to perform? Thank you in advance. sensor_name: visir/ahi composites: true_co...

Geo2Grid v 1.0.1 Sunz and Rayleigh Correction
Good Day, once again I would like to ask questions regarding the correction of ahi bands using Geo2Grid. Specifically, are there any big changes regarding this from the previous version (v. 1.0.0)? Because when I tried to process some bands, the resulting processed tiff images have zero values for w...

Re: Himawari-8 Cloud mask
Oh, that's great, thank you. It seems that you already answered this from the last discussion, and I just remembered it, my bad. My question now is would converting it to float32 affect the correction process for 'sunz_corrected' and 'rayleigh_scattering' we tried from the previous discussion or it ...

Re: Himawari-8 Cloud mask
Hello, thanks for the reply. My situation now is that if I want to apply algorithms in order to produce cloud mask, I want to apply it to the pixel values with the "right unit." Of course reflectance values does not have a unit, what I mean is the result from the ratio itself with decimals...

Himawari-8 Cloud mask
Hello,
I'm now researching about the cloud masking techniques applied to Himawari-8 satellite images. I want to ask if there is a feature in Geo2Grid for cloud masking for Himawari-8 or anything related to it.
Thank you.

Re: No filenames found for reader ahi_hsd
It works now, thanks! However, I don't think B04 and B05 were processed properly as there was a warning for both B04 and B05, namely: Warning for B04 and B05: [2019-07-29 08:39:23,912] : PID 30 : WARNING : pyspectral.rayleigh : get_reflectance : Effective wavelength for band B04 outside 400-800 nm r...

Re: No filenames found for reader ahi_hsd
Hello! It seems that the corrections were applied now. However, when trying to process for the corrected images of B01, B02, B04, and B05, the process asks for B03. And even though B03 is in the same folder/directory, it seems to not work and return an error. .log for B03_corrected (no error) [2019-...
