Re: MODIS SIN Grid data(MOD16A2) visualization.

1) You used (lon, lat) and (lons, lats) coordinates, both of them wgs84, and asked why this map is shifting. It is impossible to understand "simple and straight" point when we follow jupyter notebook you shared. 2) Of course, maps will shift if you are projecting them and there is no solut...

Even though I followed quality standards defined in the user handbook, there are LST values that are unreasonable above physical limits, like more than 100 °C in Aqua night products. The exact pixel has a much more reasonabl...
