Description

The MOD17A2H V6.1 Gross Primary Productivity (GPP) product is a cumulative 8-day composite with a 500m pixel size. The product is based on the radiation-use efficiency concept and can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation.

Bitmask for Psn_QC

Bit 0: MODLAND QC bits
- 0: Good quality
- 1: Other quality
Bit 1: Sensor
- 0: Terra
- 1: Aqua
Bit 2: Dead detector
- 0: Detectors apparently fine for up to 50% of channels 1, 2
- 1: Dead detectors caused >50% adjacent detector retrieval
Bits 3-4: Cloud state
- 0: Significant clouds NOT present (clear)
- 1: Significant clouds WERE present
- 2: Mixed cloud present on pixel
- 3: Cloud state not defined, assumed clear
Bits 5-7: 5-level confidence quality score
- 0: Very best possible
- 1: Good, very usable, but not the best
- 2: Substandard due to geometry problems - use with caution
- 3: Substandard due to other than geometry problems - use with caution
- 4: Couldn't retrieve pixel (NOT PRODUCED AT ALL - non-terrestrial biome)
- 7: Fill Value
