“…These results indicate that the VIIRS variability is less than 0.6% per year for RSB and 2.5% for shortwave infrared (SWIR) bands [8,9]. The difference between the absolution calibration of VIIRS and MODIS for most bands are within 2.0% [9,10,30,32]. The global surface classification type products generated using S-NPP VIIRS data maintain (78.64% ± 0.57%) overall accuracy [23].…”

“…The Libya 4 site is often selected as a calibration study site based on its high spatial uniformity and temporally invariant surface cover properties for stable reflectance and bidirectional reflectance distribution function (BRDF) [4,5,[8][9][10]. This site is located in an arid region and thus has a low probability of cloudy weather and precipitation.…”

“…Some studies in the past have also demonstrated independent techniques for validation of VIIRS on-orbit calibration using Earth view data. Uprety et al [10,30,31] have analyzed the stability of VIIRS RSB in the past few years through inter-comparison with Aqua MODIS and Landsat 8 OLI at Libya 4, Sudan 1, Dome C, and Ocean sites. Wu et al [9] have done an assessment of the radiometric calibration stability of the first three years of VIIRS visible and near infrared spectral bands using measurements from Suomi-NPP VIIRS and Aqua MODIS simultaneous nadir overpasses over the Libya 4 and Dome C sites.…”

Abstract:In this study, the observations from S-NPP VIIRS Day-Night band (DNB) and Moderate resolution bands (M bands) of Libya 4 and Dome C over the first four years of the mission are used to assess the DNB low gain calibration stability. The Sensor Data Records produced by NASA Land Product Evaluation and Algorithm Testing Element (PEATE) are acquired from nearly nadir overpasses for Libya 4 desert and Dome C snow surfaces. A kernel-driven bidirectional reflectance distribution function (BRDF) correction model is used for both Libya 4 and Dome C sites to correct the surface BRDF influence. At both sites, the simulated top-of-atmosphere (TOA) DNB reflectances based on SCIAMACHY spectral data are compared with Land PEATE TOA reflectances based on modulated Relative Spectral Response (RSR). In the Libya 4 site, the results indicate a decrease of 1.03% in Land PEATE TOA reflectance and a decrease of 1.01% in SCIAMACHY derived TOA reflectance over the period from April 2012 to January 2016. In the Dome C site, the decreases are 0.29% and 0.14%, respectively. The consistency between SCIAMACHY and Land PEATE data trends is good. The small difference between SCIAMACHY and Land PEATE derived TOA reflectances could be caused by changes in the surface targets, atmosphere status, and on-orbit calibration. The reflectances and radiances of Land PEATE DNB are also compared with matching M bands and the integral M bands based on M4, M5, and M7. The fitting trends of the DNB to integral M bands ratios indicate a 0.75% decrease at the Libya 4 site and a 1.89% decrease at the Dome C site. Part of the difference is due to an insufficient number of sampled bands available within the DNB wavelength range. The above results indicate that the Land PEATE VIIRS DNB product is accurate and stable. The methods used in this study can be used on other satellite instruments to provide quantitative assessments for calibration stability.

“…More details on the PICSs can be found in Helder et al (2010). In the past these sites have been widely used in post launch calibration and validation of satellite sensors (e.g., Smith and Cox, 2013;Mishra et al, 2014;Sun et al, 2014;Uprety and Cao, 2015). Fortunately, in this area the impact of the ERS-2 tape recorder failure in June 2003 is quite small, so that the time series are almost complete with only a short gap in 2003.…”

Abstract. The Global Ozone Monitoring Experiment (GOME) on-board the second European Remote Sensing satellite provided measurements of atmospheric constituents such as ozone or other trace gases for the 16 year period from 1995 to 2011.In this paper we present a detailed analysis of the long-term performance of the sensor and introduce the new homogenized and fully calibrated level 1 product which has been generated using the recently developed GOME Data Processor level-0-to-1b (GDP-L1) Version 5.1. By means of the various in-flight calibration parameters we monitor the behavior and stability of the in-5 strument during the entire mission. Severe degradation of the optical components has led to a significant decrease in intensity in particular in channels 1 and 2 covering the spectral ranges of 240-316 nm and 311-405 nm, respectively. Thus, a soft correction based on using the sun as a stable calibration source is applied. Revision and optimization of other calibration algorithms such as the wavelength assignment, polarization correction, or dark current correction resulted in an improved and homogeneous level 1 product that can be regarded as the European satellite reference data for successor atmospheric composition sensors and 10 that provides an excellent prerequisite for further exploitation of GOME measurements.

Characterizing the information content of cloud thermodynamic phase retrievals from the notional PACE OCI shortwave reflectance measurements

We rigorously quantify the probability of liquid or ice thermodynamic phase using only shortwave spectral channels specific to the National Aeronautics and Space Administration's Moderate Resolution Imaging Spectroradiometer, Visible Infrared Imaging Radiometer Suite, and the notional future Plankton, Aerosol, Cloud, ocean Ecosystem imager. The results show that two shortwave‐infrared channels (2135 and 2250 nm) provide more information on cloud thermodynamic phase than either channel alone; in one case, the probability of ice phase retrieval increases from 65 to 82% by combining 2135 and 2250 nm channels. The analysis is performed with a nonlinear statistical estimation approach, the GEneralized Nonlinear Retrieval Analysis (GENRA). The GENRA technique has previously been used to quantify the retrieval of cloud optical properties from passive shortwave observations, for an assumed thermodynamic phase. Here we present the methodology needed to extend the utility of GENRA to a binary thermodynamic phase space (i.e., liquid or ice). We apply formal information content metrics to quantify our results; two of these (mutual and conditional information) have not previously been used in the field of cloud studies.
