Re: MCD19A2 AOD data preprocessing
Hello, I am really not sure on how you get get a csv file for AOD. Because of the multiple dimensions of the file, this product is not available in our AppEEARS tool. I am not sure if ArcMap can do that or not. You may have to check with the software documentation for many of these questions: https:...

Re: Slow Download of HDF files using urllib
Good Morning,
Could you send us you script and we can take a look to see what may be going on. I can't think of any changes on e4ftl01.cr.usgs.gov that may have caused this.
Thanks,
Brett

Re: MODIS MOD09A1 Product negative reflectances
Hi Niklas, Sorry, but I don't think there is much that can be done about that, the MOD09 products are not recommended for water pixels. The "anomalies" that you've identified, e.g. negative reflectance values, are known issues in MODIS along with many other Surface Reflectance products suc...

Re: Error loading into memory HLS data
Hi Charlie, We've updated the HLS_Tutorial.ipynb to include a try loop around reading of the HLS files via https. There seems to be some sort of network issue that can cause that error, and it appears to be independent of the code being executed in the notebook. We would recommend adding a retry loo...
