The HYPERNETS project has developed a new hyperspectral radiometer integrated in automated networks of water and land bidirectional reflectance measurements for satellite validation. A detailed uncertainty budget was measured in the lab for these instruments, and these uncertainties are propagated from product to product using the CoMet toolkit within the hypernets_processor. All HYPERNETS products are provided as obsarray-compatible digital effects tables. For the HYPERNETS vicarious calibration study, the uncertainties in these files are also propagated to TOA using punpy.

❔ What is HYPERNETS?

❕ How is the CoMet Toolkit contributing to HYPERNETS?

A detailed uncertainty budget was measured in the lab for the HYPERNETS instruments. These uncertainties were then propagated from product to product using the CoMet Toolkit within the hypernets_processor.

All HYPERNETS products are provided as obsarray-compatible digital effects tables. For the HYPERNETS vicarious calibration study, the uncertainties in these files are also propagated to TOA using punpy.
