Quantifying the impact of aerosol scattering on the retrieval of methane from airborne remote sensing measurements [PDF]

Atmospheric Measurement Techniques, 2020
As a greenhouse gas with strong global warming potential, atmospheric methane (CH4) emissions have attracted a great deal of attention. Although remote sensing measurements can provide information about CH4 sources and emissions, accurate retrieval is ...

Quantifying Volumetric Scattering Bias in ICESat‐2 and Operation IceBridge Altimetry Over Greenland Firn and Aged Snow

Earth and Space Science
The Ice, Cloud, and Land Elevation Satellite‐2 (ICESat‐2) mission has collected surface elevation measurements for over 5 years. ICESat‐2 carries an instrument that emits laser light at 532 nm, and ice and snow absorb weakly at this wavelength.

Adapting Prediction Models to Bare Soil Fractional Cover for Extending Topsoil Clay Content Mapping Based on AVIRIS-NG Hyperspectral Data

Remote Sensing
The deployment of remote sensing platforms has facilitated the mapping of soil properties to a great extent. However, the accuracy of these soil property estimates is compromised by the presence of non-soil cover, which introduces interference with the ...

Hyperspectral Bare Soil Index (HBSI): Mapping Soil Using an Ensemble of Spectral Indices in Machine Learning Environment

Land, 2023
Spectral remote-sensing indices based on visible, NIR, and SWIR wavelengths are useful in predicting spatial patterns of bare soil. However, identifying an effective combination of informative wavelengths or spectral indices for mapping bare soil in a ...

Towards the CO2Image mission: performance studies using AVIRIS-NG [PDF]

, 2021
<p>Monitoring of anthropogenic carbon dioxide (CO2) emission sources with air- and space-borne remote sensing instruments relies on high-spatial resolution measurements. Such observations can be achieved at the expense of decreasing the spectral resolution of the instrument, which in turn complicates CO2 retrieval techniques due to the ...

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress. [PDF]

Glob Chang Biol
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.

Assessing the spectral diversity of managed grassland in the Lower Engadin [PDF]

, 2023
Biodiversity in grasslands is decreasing, worldwide as well as in the Swiss Alpine regions, which is why effective monitoring methods are needed. Remote sensing can provide broader spatial coverage, potentially addressing the limitations of conventional ...

Comparison of Methane Detection Using Shortwave and Longwave Infrared Hyperspectral Sensors Under Varying Environmental Conditions

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Methane is a prevalent greenhouse gas with potent heat trapping capabilities, but methane emissions can be difficult to detect. Hyperspectral imagery is an effective method of detection which can be used to locate methane emission sources, as well as ...
