HICO Ocean Color Reprocessing 2018.0

HICO Ocean Color Reprocessing 2018.0

Introduction

The Ocean Biology Processing Group (OBPG) completed a full-mission ocean color reprocessing of the data from the Hyperspectral Imager for the Coastal Ocean Sensor (HICO). This reprocessing is part of a multi-mission effort to update instrument calibrations and vicarious calibrations only. Sensor-independent changes are detailed in the R2018.0 Ocean Color Reprocessing General Description. Here we describe the HICO sensor-specific details of the reprocessing.

Sensor-specific Processing Details

Source Data

Reprocessing R2018.0 starts from the HICO Level-1B files. The Level-1B source files are updated to version 2 to support the conversion of data from HDF format to netCDF4.

Instrument Calibration

The HICO instrument calibration is unchanged.

Vicarious Calibration

A vicarius calibration, as described in Ibrahim, et.al. 2018, was performed for this reprocsssing.

Level-2 Processing

The product algorithms and product suites are identical to past versions. However, in R2018.0, the data format has changed from HDF to netCDF-4.
