Microclimf: Fast modelling of microclimate across real landscapes in R

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Many ecological studies require climate data, but readily available datasets are poor surrogates for the conditions that organisms experience in nature. Understanding the climatic conditions experienced by organisms requires modelling microclimate rather than relying on coarse, station‐based climate data.

Rotational Spectral Unmixing of Exoplanets: Degeneracies between Surface Colors and Geography

open access: yes, 2017
Unmixing the disk-integrated spectra of exoplanets provides hints about heterogeneous surfaces that we cannot directly resolve in the foreseeable future.

Monitoring surface albedo change with Landsat

open access: yesGeophysical Research Letters, 1977
A pronounced decrease of the surface albedo (reflectivity) has been observed in an area in the Northern Sinai, fenced‐in in the summer of 1974. Analysis of the LANDSAT Multispectral Scanner System digital data from an April 1977 pass indicates a reduction in the albedo in the exclosure by Δa = 0.06, or 13%, as compared to the outside, which continues ...

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

open access: yesBoreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

The Acts of Eadburg: drypoint additions to Oxford, Bodleian Library, MS Selden Supra 30

open access: yesEarly Medieval Europe, EarlyView.
In 1913, two drypoint additions were identified in Oxford, Bodleian Library, MS Selden Supra 30 (SS30), an eighth‐century Southumbrian copy of the Acts of the Apostles. It was suggested that these additions, cut into the membrane of p. 47, were abbreviations of the Old English female name, Eadburg. Just over a century later, many more drypoint markings

Optimal Nodes Selectiveness from WSN to Fit Field Scale Albedo Observation and Validation in Long Time Series in the Foci Experiment Areas, Heihe

open access: yesRemote Sensing, 2015
To evaluate and improve the quality of land surface albedo products, validation with ground measurements of albedo is crucial over the spatially and temporally heterogeneous land surface. One of the essential steps for satellite albedo product validation

Surface Albedo over the Sahel from METEOSAT Radiances

open access: yesJournal of Climate and Applied Meteorology, 1985
Abstract A method to estimate surface albedo in the African Sahel is proposed and discussed. This method, which uses METEOSAT imagery and routine surface global radiation measurement is shown to be relevant for climatological studies. The accuracy in the estimated albedos is analysed with respect to the intervening physical parameters. It is shown that

Rational determination of real‐life UV exposure across latitudes: An extended Diffey‐based model integrating behavioural factors

open access: yesInternational Journal of Cosmetic Science, EarlyView.
This study models real‐life UVB and UVA exposure across latitudes and seasons using an extended Diffey framework with behavioural corrections. Findings reveal predictable dose patterns and support pragmatic SPF and UVA‐PF caps, offering a quantitative basis for realistic photoprotection and regulatory discussion.
