A large set of experimental data was obtained during experiments aimed on study of the interaction between the water surface and the atmosphere using microwave radiometers. The experiments were carried out on the oceanographic platform of the Black Sea Hydrophysical Testing Ground of the Russian Academy of Science in the period from 2005 to 2019. Over the years, the set of radiometric instruments changed, but radiometers with a frequency of about 36 GHz were used in each experiment, so the results are presented specifically for this frequency. A qualitative comparison of the measurement results with model calculations and other experimental studies of anisotropy are carried out. It is shown that there is a strong sensitivity of changes in the radio emission of a rough water surface, both to the wind speed and to its direction at different incidence angles.","PeriodicalId":223225,"journal":{"name":"2020 16th Specialist Meeting on Microwave Radiometry and Remote Sensing for the Environment (MicroRad)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127381227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To resolve this issue, a lot of research efforts have been devoted to developing resolution enhancement methods which retrieve a high-resolution image out of its low-resolution degraded versions. In this paper, we consider a nonlocal total variation (NLTV) based super-resolution method which handles low-resolution images with geometric deformations. In particular, we apply the framework of alternating direction method of multipliers (ADMM) to deduce an effective algorithm, which involves soft thresholding and gradient descent. Effectiveness and robustness to noise of the proposed method are verified by various numerical experiments.","PeriodicalId":223225,"journal":{"name":"2020 16th Specialist Meeting on Microwave Radiometry and Remote Sensing for the Environment (MicroRad)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125411435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Statistical analysis of the opacity air mass pairs have been used as measures of the tip curve quality, but the choice of acceptance criteria has been subjective. An analysis of the tipping curve acceptance criteria was accomplished by simulation of a total power radiometer under non stratified conditions due to perturbations of water vapor content. Relationships between the root mean square error (RMSE) in zenith brightness temperature and regression coefficient were examined. While the RMSE decreased with increasing regression coefficient, a stringent acceptance criteria did not ensure accuracy likely due to the presence of net horizontal gradients. On the other hand, for radiometers with multiple channels the standard deviation of brightness temperature measurements of a reference black body, also known as spectral consistency, was found to be a robust indicator of calibration accuracy.","PeriodicalId":223225,"journal":{"name":"2020 16th Specialist Meeting on Microwave Radiometry and Remote Sensing for the Environment (MicroRad)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129333331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiometer carries out conical scanning at the incidence angle of 65° and receives the outgoing radiation of the Earth at 31 channels at frequencies from 10 to about 190 GHz. Swath width is 2500/1500 km. The parameters of the ocean, land surface, and troposphere are retrieved from brightness temperatures with vertical and horizontal polarizations TB(ν) measured at imager frequencies ν = 6.9, 10.65, 18.7, 23.8, 31.5, 36.5, 42.0, 48.0, and 91,65 GHz. Measurements at sounder frequencies (10 channels in the oxygen absorption band 52–58 GHz and three channels near the strong resonance line of water vapor 183.31 GHz) provide information on air temperature and humidity of various layers in the upper troposphere - middle stratosphere. Manifestations of synoptic scale dynamic atmospheric phenomena on global TB charts at imager frequencies visualize their structure and development.

It allows to compare and characterize the ozone spectra over an extended period of time and covering a wide range of meteorological conditions. We show that the spectra derived from the Acqiris AC240 is systematically biased compared to other state-of-the-art spectrometers. It has a different spectral slope and a negative bias at the line center on the order of 8 percent. The bias evolves with the atmospheric opacity and originates from various sources. Using some simple corrections, we show that the bias from the AC240 can be corrected during data processing which is of high interest for the numerous time series derived from this back-end.","PeriodicalId":223225,"journal":{"name":"2020 16th Specialist Meeting on Microwave Radiometry and Remote Sensing for the Environment (MicroRad)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115925886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A unique feature of the radiometer is the fully digital back-end which permits direct computation of the third and fourth Stokes parameters (i.e., real and imaginary part of the correlation of signal at horizontal and vertical polarizations). The SMAP conical scanning geometry has provided the opportunity to look at the global distribution of the fourth Stokes parameter at constant incidence angle (40 degrees at the surface). A striking feature of these maps is the existence of a strong (± 10 K peak-to-peak) spurious signal at coastlines. There is also a weak coupling to Faraday rotation. This paper reports research to explain the existence of these spurious signals.","PeriodicalId":223225,"journal":{"name":"2020 16th Specialist Meeting on Microwave Radiometry and Remote Sensing for the Environment (MicroRad)","volume":"652 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127540751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effective emissivity Eeff harmoniously corresponds to the radiation transfer model and the equations that can be used for sounding the Earth from spacecraft.
