Alps glacier velocities 2013-2015 (Landsat 8)

open access: yes, 2019
This dataset contains the median glacier surface velocity for the Alps for the years 1999-2003 (Landsat 7 SLC-ON only). The velocities has been obtained by feature-tracking of Landsat images spaced 1 year apart. The folder contains the following fields at 30 m resolution in GeoTiff format: - the velocity magnitude 'vel' (meters per year) - the x/y ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

QWIPs, SLS, Landsat and the International Space Station [PDF]

open access: yes
In 1988 DARPA provided funding to NASAs Goddard Space Flight Center to support the development of GaAs Quantum Well Infrared Photodetectors (QWIP). The goal was to make a single element photodetector that might be expandable to a two-dimensional array ...

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

open access: yesJournal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Gap-filling of land surface temperature in arid regions by combining Landsat 8 and 9 imageries

open access: yesEnvironmental Research Communications
Land surface temperature (LST) is an important factor in land monitoring studies, but due to the presence of clouds, dust and sensor issues, there are missing values.

Production of a water quality map of Saginaw Bay by computer processing of LANDSAT-2 data [PDF]

open access: yes
Surface truth and LANDSAT measurements collected July 31, 1975, for Saginaw Bay were used to demonstrate a technique for producing a color coded water quality map.
