GSICS Users Workshop 2019

The GSICS Users Workshop 2019 was organized a part of ITSC-XXII in San Savur Canada on 1 Nov 2019. The meeting had over 50 attendees and 10 talks. Talks covered various topics relevant to the application of GSICS algorithms and products in IR VIS MW and UV wavelengths.

Talk1. Mitch Goldberg, GSICS EP Chair started the meeting by providing an introduction about the GSICS. The introduction included purpose, history of GSICS and showed how GSICS style instrument monitoring is critical to the users of Earth Observation data. Channels of GSICS knowledge and data sharing included GSICS product catalog, GSICS Newsletter and the yearly State of Observing System report that GSICS Delivers to the CGMS. This report summarizes the performance of each instrument monitoring by the individual GPRCs. Mitch further indicated GSICS forays into the WMO Integrated Observing System ( wigos). GSICS is now a component of the WIGOS and has prepared documents that are currently being reviewed by the WIGOS.

Talk2. Dave Tobin from the University of Wisconsin is a key member of the CrIS calibration team. CrIS is used by the GSICS community as a in-orbit reference for the IR instruments. He spoke about the attributes of a GSICS reference instrument. Dave's talk touched on a very important topic in GSICS community i.e the selection of In-orbit references. Dave suggested a set of attributes that can help decide on a reference instrument.

Talk3. Dorothea Coppins from EUMETSAT gave a talk focused on GSICS IR inter-calibration activities. The three main GSICS IR products include Classical GSICS Products, GSICS Prime Product, GSICS IR Reference and Future GSICS Products . Dorothea provided an overview of recent changes to processing to IASI-A after it entered its end of life phase. She suggested GSICS members to switch to IASI-B or IASI-C as reference. In summary the IASI-A has the following behaviour currently.
  • SWIR: V. small positive differences (<<0.1K)
  • MWIR: V. small positive differences (<<0.1K)
  • LWIR window: Small negative differences (<~0.1K)
  • LWIR absorption: Larger negative differences (<~0.3K)
In the future KMA and CMA are expected to provide intercalibration products of AMI and FY-3.

Talk4. Tiger Yang from NOAA gave an overview of Lunar Calibration. His talk touched on various key issues, A key issue for microwave cubesats and small satellite constellation is a consistency calibration algorithm. Permanent Reference Target (PRT) with high stability and well-known microwave brightness temperature can not only help to evaluate the instrument calibration accuracy, it can also being used to evaluate the long-term calibration stability of microwave sensors. Radiation of the Moon is very stable in microwave spectrum, attribute to its stable geophysical property. The only factors that change the magnitude of lunar microwave radiation in satellite observations are its surface temperature, which is determined by its phase angle, and its position in the Field of View (FOV). Therefore, there is potential to take the Moon as PRT to evaluate the calibration accuracy and assess the long-term calibration stability for microwave radiometers. In this study, microwave brightness temperature simulation model for moon’s disk was developed and validated based on ATMS space view observations. To demonstrate the effectiveness of proposed lunar calibration model, 5 years lunar observations from NPP ATMS were collected and evaluated by the model simulations. Results show that ATMS calibration accuracy and stability can be well assessed by taking the moon as a reference calibration target
