Thanks for the tile info Hawthorne. I have found those values in many random files since you brought that to our attention. We have contacted the folks at LDOPE who help develop the products and also specialize in the QC. As soon as we hear back from them I will let you know. Thanks for your patienc...

Hello,
Thanks for bringing this to our attention, do you have a specific Granule ID, we would like to show this to the MODIS Science Team and make them aware of this. Our first thought is maybe the bits got inverted, but either way something is amiss.
Thanks,

Hi, Sorry for the misinformation with this. The more precise size of the what is referred to as 500 meter MODIS pixel is actually 463.3127 meters. Each MODIS 500 meter product will have 2400 x 2400 pixels. The native format for the gridded MODIS products are Sinusoidal and this makes the MODIS image...

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:...

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,

Hello, Yes, the day mentioned is the first day of the composite period, so in your example the period would be from January 1 through the 8th of January. This is true with all MODIS/VIIRS products, with one exception. That exception is the MCD43 BRDF/Albedo products. Those are 16 day products, but t...

Could you attach your python code and we can take a look, Also, could you attach the text file then we can see where you compile it from. If you would like you could send it to the LPDAAC email: lpdaac@usgs.gov
Thanks,

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...

Hi Hina, The MCD43A3 is available through AppEEARS: https://lpdaac.usgs.gov/products/mcd43a3v061/ The MCD43A3 contains the 7 MODIS Land Bands and 3 broadbands in both Black-Sky and White_Sky Albedo. AppEEARS will allow you to perform a lat long Point search or an area. The point search would bring b...

Hi Mauricio,
Thanks for your patience. The CMR cloud library has been updated so it should be reconciled with our on-prem Data Pool.
Thanks again for your patience and informing us about this.
