Multispectral Radiometer Data


Multispectral data is collected using the Skye NDVI and PRI sensors. These are point radiometers, integrating a reflectance signal over the field of view. Note that we also generate NDVI and PRI measurements from the hyperspectral and UAV datasets. For plot level summaries, these will be differentiated by the 'methods' field.

Currently, only raw data are available. The pipeline for processing these data has been developed but still needs to be tested and updated. See terraref/computing-pipeline#150.

Sensor information:

For details about using this data via Clowder or Globus, please see Data Access section.

Data Access

Level 1 data

NA Will be added to Geostreams for the Nov 2018 release.

Level 2 data


Level 3 data

Plot level summaries will be inserted into BETYdb.
