[1] The fundamental measurement of the Tropospheric Emission Spectrometer (TES) on board the Aura spacecraft is upwelling infrared spectral radiances. Accurate TES retrievals of surface and atmospheric parameters such as trace gas amounts critically depend on well-calibrated radiance spectra. On-orbit TES nadir observations were evaluated using carefully selected, nearly coincident spectral rad...

Land surface temperature (LST) is a key variable in the study of the energy exchange between the land surface and the atmosphere. Among the different methods proposed to estimate LST, the quadratic split-window (SW) method has achieved considerable popularity. This method works well when the emissivities are high in both channels. Unfortunately, it performs poorly for low land surface emissivit...

This paper compares the calibration consistency of the spectrally-matched thermal emissive bands (TEB) between the Suomi National Polar-orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) and the Aqua Moderate Resolution Imaging Spectroradiometer (MODIS), using observations from their simultaneous nadir overpasses (SNO). Nearly-simultaneous hyperspectral measurements ...

Abstract. The Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) satellite mission is a joint endeavour developed by the European Space Agency (ESA) Japan Aerospace Exploration (JAXA) features 94 GHz Doppler Cloud Profiling Radar. This paper presents theoretical basis of cloud precipitation microphysics (C-CLD) EarthCARE Level 2 (L2) algorithm. C-CLD algorithm provides best estimates ver...

The Land Surface Temperature (LST) product of AATSR was validated with in situ measurements at two thermally homogeneous sites: Lake Tahoe, CA/NV, USA and a large rice field close to Valencia, Spain. The AATSR LST product is based on the split-window technique using the nadir view of the 11 and 12 μm channels. The algorithm coefficients are provided for 13 different land cover classes plus one ...

This paper presented a rigorous mathematical model based on orbital parameters for correction of the geo-rectified images such as Ikonos Geo, where the geometry of image at the time of imaging is lost and minimum information regarding the satellite movement in its orbit is available. Based on this model, the geo-rectified image is converted back to its geometry at the time of imaging at first. ...

Mitochondrial DNA variability in two Slavonic-speaking populations of the northwestern Balkan peninsula, Bosnians (N = 144) and Slovenians (N = 104), was studied by hypervariable segments I and II (HVS I and II) sequencing and restriction fragment-length polymorphism (RFLP) analysis of the mtDNA coding region. The majority of the mtDNA detected in Southern Slavonic populations falls into the co...

Vertical structure is an important parameter not only for assessment of the naturalness a forest and several functional parameters, such as biodiversity or protection from avalanches rockfall, but also estimating biomass/carbon content. This study analyses options assessing vertical by using airborne (ALS) spaceborne LiDAR data (GEDI) in mountainous near-natural Austrian Alps. Use GEDI waveform...

[1] To estimate sea ice thickness over a large spatial scale is a challenge. In this paper, we propose a direct approach to effectively estimate sea ice thickness over a large spatial area of the Bohai Sea using EOS MODIS data. It is based on the model of an exponential relation between albedo and thickness of sea ice. Eighteen images of EOS MODIS L1B data in the 2009–2010 winter were used to e...

The European Space Agency (ESA) successfully launched the Soil Moisture and Ocean Salinity (SMOS) mission in November 2, 2009. SMOS uses a new type of instrument, a synthetic aperture radiometer named MIRAS that provides full-polarimetric multi-angular L-band brightness temperatures, from which regular and global maps of Sea Surface Salinity (SSS) and Soil Moisture (SM) are generated. Although ...
