Question: MOD16A2 Unit Conversion

Re: MOD16A2 Unit Conversion

Hello,
The values in the .csv file are already scaled. However, the geotiff files are not supposed to be scaled.
Thanks,
Brett

Re: MOD16A2 Unit Conversion

Hi,
Yes the scaling factor is 0.1 (divide by 10). If there seems to be some erroneous numbers you may want to check with the QA bits to see if those pixels are of questionable quality.
Thanks,

Re: VIIRS Vegetation version 2 in datapool / CMR

Hi Val, Sorry for the issues accessing the VIIRS product. Unfortunately, the VIIRS Version 2 products will not be available in the Data Pool.

Question: MODIS LAI valid range

Re: MODIS LAI valid range

Hi Jeongho,
I am thinking those specific pixels are of questionable quality. Did you have a chance to look at the QA information for those pixels? If you could send me a specific Granule ID with the H/V number and date I could take a look and see what may be going on.
Thanks,
Brett

Re: MOD09A1 on 2001-06-18 missing

Hi Niklas, Sorry for the delay. We contacted the Science Team and the product developers on the corruption issues. Technically they don't consider it corrupted as much as the inability and challenges of the sensor to acquire data in the very high latitudes. They said: "the light blue area is ei...

Re: GEDI LAI

Hello, Unfortunately, LAI is not a layer in the GEDI L2B dataset. The most similar (but not interchangeable) layer would be the plant area index (PAI). You can view the dataset layers in the GEDI L2B Data Dictionary: https://lpdaac.usgs.gov/documents/980/gedi_l2b_dictionary_P003_v2.html?_ga=2.184374...

Re: MOD16A2.061 availability on Google Earth Engine

Hi,
That would be a question for Google Earth Engine. GEE is not an LPDAAC site so we would have no idea on this. Because the MOD16A2 is a temporary product they may not. But that would be a questions for them.
Thanks,
Brett
