The infrared instrument for sea surface temperature (iriss): An innovative and simplified design for measuring ocean surface skin temperature

The InfraRed Instrument for Sea Surface temperature (IRISS) is a simplified design that uses a one-point in situ calibration and separate sensors to measure the sea and sky radiance. The standard wavelength band (9.6-11.5 microns) and a so-called optimal band (7.5-7.85 microns) were evaluated by comparison to the Remote Ocean Surface Radiometer (ROSR) during an extensive field deployment. The dataset structure is CSV files containing time series with variable names at the beginning of the file. Potential reuse includes verifying the performance.  There are no legal or ethical considerations.

## Description of the data and file structure

The importance of accurate measurements of ocean skin temperature, *T~skin~*, is increasingly recognized for a wide range of air-sea interaction research. However, *T~skin~* measurements currently are made using complex infrared radiometer systems that have been limited to ship deployments. Major measurement challenges are *in situ* calibration, a separate sky measurement to correct for reflected downwelling radiance, and emissivity uncertainty. The InfraRed Instrument for Sea Surface temperature (IRISS) is a simplified design that uses a one-point *in situ* calibration and separate sensors to measure the sea and sky radiance. The standard wavelength band (9.6-11.5 mm) and a so-called optimal band (7.5-7.85 mm) were evaluated by compa...,
