Assessment of the aerosol optical depths measured by satellite-based passive remote sensors in the Alberta oil sands region [PDF]

Atmospheric Chemistry and Physics, 2017
Several satellite aerosol optical depth (AOD) products are assessed in terms of their data quality in the Alberta oil sands region. The instruments consist of MODIS (Moderate Resolution Imaging Spectroradiometer), POLDER (Polarization and Directionality ...

Volcanic Hot-Spot Detection Using SENTINEL-2: A Comparison with MODIS−MIROVA Thermal Data Series [PDF]

, 2020
In the satellite thermal remote sensing, the new generation of sensors with high-spatial resolution SWIR data open the door to an improved constraining of thermal phenomena related to volcanic processes, with strong implications for monitoring ...

Climate and Socio‐Sexual Environment Predict Interpopulation Variation in Chemical Signaling Glands in a Widespread Lizard

Integrative Zoology, EarlyView.
High phenotypic variation in femoral pore number across 55 populations of Podarcis muralis is best explained by a combination of positive allometry (size) and the local intensity of sexual selection (sexual dimorphism in body size, SSD) or local climatic conditions, notably temperature and vegetation density.

Vegetation NDVI Linked to Temperature and Precipitation in the Upper Catchments of Yellow River [PDF]

, 2012
Vegetation in the upper catchment of Yellow River is critical for the ecological stability of the whole watershed. The dominant vegetation cover types in this region are grassland and forest, which can strongly influence the eco-environmental status of ...

Opposite geographical body size patterns in two subspecies of spur‐thighed tortoises in North Africa match climatic niche divergence

Journal of Zoology, EarlyView.
We investigated body size variation in two North African subspecies of spur‐thighed tortoises, Testudo graeca whitei and T. g. marokkensis, in relation to environmental gradients. The subspecies exhibited opposite geographical size patterns consistent with their divergent climatic niches: T. g. marokkensis followed Bergmann's rule, while T. g.

Modelling frost generates insights for managing risk of minimum temperature extremes

Weather and Climate Extremes, 2020
Frosts and extreme minimum temperature events cause significant damage to grapevines. In the Victorian vine growing regions of Australia, these events may cause complete wipe-out of a season's grape production, and millions of dollars of losses. Frost is

Spatiotemporal changes of snow cover over the Tibetan plateau based on cloud-removed moderate resolution imaging spectroradiometer fractional snow cover product from 2001 to 2011

, 2013
Snow cover changes over the Tibetan plateau (TP) are examined using moderate resolution imaging spectroradiometer (MODIS) daily fractional snow cover (FSC) data from 2001 to 2011 as well as in situ temperature data.

Evaluating the Spatial Representativeness of the MODerate Resolution Image Spectroradiometer Albedo Product (MCD43) at AmeriFlux Sites [PDF]

Remote Sensing, 2019
Land surface albedo is a key parameter in regulating surface radiation budgets. The gridded remote sensing albedo product often represents information concerning an area larger than the nominal spatial resolution because of the large viewing angles of the observations.

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

Marine Mammal Science, EarlyView.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

An Evaluation of MODIS-Retrieved Aerosol Optical Depth over AERONET Sites in Alaska

Remote Sensing, 2018
The air quality monitoring network in Alaska is currently limited to ground-based observations in urban areas and national parks, leaving a large proportion of the state unmonitored.
