“…It is a CEOS endorsed calibration site. The site has excellent temporal stability and spatial uniformity (Cao et al, 2010;Uprety & Cao, 2011. It has been studied rigorously due to its unique characteristics such as, high altitude; high reflectance; high percentage of cloud-free time; atmosphere with very low infrared sky emission, low water vapor content and low aerosol and dust content.…”

“…Works reported in [8,[13][14][15][16][17] have shown and identified stable EV targets that serve the above mentioned purpose. The Dome C (75.102˝S, 123.395˝E) is one such EV target that has been characterized for Long Wave InfraRed (LWIR) satellite retrievals [8].…”

Abstract:The S-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) instrument, a polar orbiting Earth remote sensing instrument built using a strong MODIS background, employs a similarly designed on-board calibrating source-a V-grooved blackbody for the Thermal Emissive Bands (TEB). The central wavelengths of most VIIRS TEBs are very close to those of MODIS with the exception of the 10.7 µm channel. To ensure the long term continuity of climate data records derived using VIIRS and MODIS TEB, it is necessary to assess any systematic differences between the two instruments, including scenes with temperatures significantly lower than blackbody operating temperatures at approximately 290 K. Previous work performed by the MODIS Characterization Support Team (MCST) at NASA/GSFC used the frequent observations of the Dome Concordia site located in Antarctica to evaluate the calibration stability and consistency of Terra and Aqua MODIS over the mission lifetime. The near-surface temperature measurements from an automatic weather station (AWS) provide a direct reference useful for tracking the stability and determining the relative bias between the two MODIS instruments. In this study, the same technique is applied to the VIIRS TEB and the results are compared with those from the matched MODIS TEB. The results of this study show a small negative bias when comparing the matching VIIRS and Aqua MODIS TEB, implying a higher brightness temperature for S-VIIRS at the cold end. Statistically no significant drift is observed for VIIRS TEB performance over the first 3.5 years of the mission.

“…The site has the following characteristics that make it very suitable for radiometric calibration and validation of satellite sensors: surface is flat and covered with uniformly distributed, permanent snow; temperatures are extremely cold and stable, except for seasonal variability; skies are clear most of the time, with more than 75% of days being cloud free; atmosphere above the site has low water vapor and aerosol loading, thus atmospheric effects are small. Previous studies, based on observations from several satellite instruments deployed by various countries, have shown that the Dome C site is generally stable in the long term [1].…”

In this study, two methods were used to evaluate radiometric calibration of the VIIRS sensor data records: (1) imaging of radiometrically stable Earth's surfaces and (2) SNO (Simultaneous Nadir Overpass) observations by VIIRS and other satellite instruments. Measurements acquired by VIIRS at the stable Dome C calibration site in Antarctica confirm that a faster-than-expected degradation of the radiometric response occurs for selected spectral bands in the visible and near-infrared region, with other bands remaining stable. SNO comparisons with MODIS show that the implemented regular updates of the radiometric calibration coefficients have stabilized the calibration and that the VIIRS and MODIS measurements are in agreement.
