Data Product Levels

Data products are processed at various levels ranging from Level 0 to Level 4. Level 0 products are raw data at full instrument resolution. At higher levels, the data are converted into more useful parameters and formats. These are derived from NASA and NEON

Level

Description

0

Reconstructed, unprocessed, full resolution instrument data; artifacts and duplicates removed.

1a

Level 0 plus time-referenced and annotated with calibration coefficients and georeferencing parameters (level 0 is fully recoverable from level 1a data).

1b

Level 1a processed to sensor units (level 0 not recoverable)

2

Derived variables (e. g., NDVI, height, fluorescence) at the level 1 resolution.

3

Level 2 mapped to uniform grid, missing points gap filled; overlapping images combined

4

'phenotypes' derived variables associated with a particular plant or genotype rather than a spatial location
