Summary: The rapid evolution of climate change effects requires satellite acquisitions with high accuracy and fine spatial resolution to assess the state of the polar area. The Copernicus Imaging Microwave Radiometer (CIMR) mission aims to observe the ocean, sea ice, and Arctic environment with specific requirements for brightness temperature measurements. A proposed antenna pattern correction (APC) algorithm corrects for the contamination of brightness temperature values caused by the use of mesh reflectors. The algorithm, based on the Jacobi Method, was tested at both K- and Ka-bands with similar performance.

Summary: A practical checkerboard target was developed for infrared camera geometric calibration based on a thorough literature review of various calibration targets. The UV-printed checkerboard target on a polished metallic alloy demonstrated the lowest mean reprojection error and root mean square error among all the targets studied. It offers better accuracy than other checkerboard targets and comparable results to prominent circular patterns.

Summary: Thermal inertia is a geophysical quantity used to characterize geological features. In this study, a new alternative called Long-term ATI (LATI) was proposed by utilizing a large ASTER data archive. The results showed that there was a strong positive correlation between LATI and the conventional ATI, suggesting that LATI is a more useful and superior alternative for characterizing surface geological features.

Summary: A new method is proposed to correct the distortion in VIIRS 24-hour data caused by lunar illumination, allowing for a consistent time series to be formed. The method is relatively simple to deploy and effective in removing periodic illumination noise while preserving meaningful information. Results from test sites show the success of the proposed method in addressing these issues.

Summary: This study proposes a new downscaling method, weighted GWR (WGWR), which considers the weights of LST descriptors. Experimental results comparing WGWR with RF and GWR using Landsat-8 and Terra ASTER data show that WGWR outperforms the other methods in terms of reducing root mean square error (RMSE) and maintaining image details at high spatial resolution.

Summary: This study utilizes Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) multispectral data to delineate bauxite deposits in the Mainpat plateau, Surguja district, Chhattisgarh, India. Specific band combinations are used to identify bauxite in the SWIR and VNIR bands of the ASTER data. Various image processing techniques are applied to the ASTER image, including atmospheric correction, minimum noise fraction, pixel purity index, n-dimensional visualiser, and spectral angle mapper, to delineate bauxite rich zones. The presence of bauxite is confirmed by comparing the spectral signatures with spectral libraries and categorizing them as bauxite and ferruginous bauxite. Geochemical analysis and XRF analysis further validate the results obtained from remote sensing technique. This study demonstrates the potential of multispectral ASTER data in mapping mineral resources.
