Thanks Liam,

that is useful information. I'll keep digging to see if there is anything specific that may point to significant differences.

Do you think there is a need to share the statistics we have? It is only for continental Europe and northern Africa. We may take a more quantitative look to ...

Hi Liam,

I definitely can. I should also be more accurate in my description. So the differences that we are seeing is in the thermal anomalies data - which are not necessarily wildfires (but could be). Differences are considered when a thermal anomaly is significantly further away, i.e. more than a ...

Hello,
I'd like to get feedback about the differences in fire algorithms. This post is a continuation based on https://forum.earthdata.nasa.gov/viewtopic.php?p=20237#p20237

Context: for VIIRS processing we use the CSPP Active Fires version: 2.1, ProcessVersionNumber = "2.5.4". However, we ...

Cool, thanks David!
I'll test it out.

Have a great day,
Conrad

Thanks David,
that does help. My final choice for running the polar2grid is the following:
polar2grid.sh -r modis_l1b -w geotiff --dtype uint16 --vis-products

and seems to output the wanted counts. I'll keep you posted if I run into any other issues.

A second question that I have is with respect ...

Hi Dave,
sorry for the silence. The output is indeed UINT16 but I'm also trying (now) to understand why there are differences in the outputs and which solution I should choose. There are a number of output options but they all seem to differ in the values produced.

1. polar2grid.sh -r modis_l1b -w ...

Hi Dave,
I'm using v3.0. Since you asked you for the logs, I also started looking into them. I am sending you two logs. The first was based on my own grid definition (which I also attach) and works when producing 'true-color' outputs. The second, I used the default polar2grid projection.

The first ...

Hi Kathy,

here is an example that I tested:
polar2grid.sh -r modis_l1b -w geotiff --dtype uint16 --no-enhance --fill-value 0 --vis-products --grid-configs ...

I have also tried using the command option to extract specific bands only but I get the same result.

Thanks,
Conrad

Hello,
I have been using polar2grid to extract and reproject MODIS data.However, the data produced is always of type Byte. Is there a function which is able to extract the MODIS data as original outputs in UINT16?

Thanks in advance for your help.
Have a great day,
Conrad
