ESSIC / CICS-MD scientists Hui Xu, Likun Wang, and Yong Chen (STAR/SMCD) have an article in press at the IEEE Transactions on Geoscience and Remote Sensing titled “Cross-Track Infrared Sounder Spectral Gap Filling Toward Improving Intercalibration Uncertainties”.
The paper focuses on the Joint Polar Satellite System (JPSS) Cross-Track Infrared Sounder (CrIS), a hyper-spectral infrared sounder used to check calibration accuracy of narrow or broadband instruments.
Despite the sounder’s full spectral resolution, it still suffers from spectral gaps that affect the accuracy of intercalibration. Xu, Wang, and Chen write about new methods to identify and fill these spectral gaps in order to extend the device’s use as a calibration standard.
