Comparison of Near-Surface Air Temperatures and MODIS Ice-Surface Temperatures at Summit, Greenland (2008–13)

A global comparison between station air temperatures and MODIS land surface temperatures reveals the cooling role of forests

NOTES AND CORRESPONDENCE Surface Melting over Ice Shelves and Ice Sheets as Assessed from Modeled Surface Air Temperatures

Summer surface melting plays an important role in the evolution of ice shelves and their progenitor ice sheets. To explore themagnitude of surfacemelt occurring overmodern ice shelves and ice sheets in a climate scenario forced by anthropogenic emissions of carbon dioxide (CO2), a coupled climate model was used to simulate the distribution of summer melt at high latitudes and project the future...

Evaluation of surface and near-surface melt characteristics on the Greenland ice sheet using MODIS and QuikSCAT data

[1] The Greenland ice sheet has been the focus of much attention recently because of increasing melt in response to regional climate warming and can be studied using Moderate Resolution Imaging Spectroradiometer (MODIS) and Quick Scatterometer (QuikSCAT) data. To improve our ability to measure surface melt, we use remote sensing data products to study surface and near-surface melt characteristi...

Upper-air temperatures around Greenland: 1964–2005

[1] A 42-year collection of 12h balloon soundings from six sites surrounding Greenland reveal distinct patterns of tropospheric and stratospheric temperature variability. Seasonal mean upper-air temperatures exhibit statistically significant correlations with surface air temperature records. Over the full 1964–2005 record, patterns of statistically significant tropospheric warming and stratosph...

Near-Surface Temperatures on Mercury and the Moonand the Stability of Polar Ice Deposits

In order to assess the thermal stability of polar ice deposits, we present model calculated temperatures of flat surfaces and surfaces within bowl-shaped and flat-floored polar impact craters on Mercury and the Moon. Our model includes appropriate insolation cycles, realistic crater shapes, multiple scattering of sunlight and infrared radiation, and depthand temperature-dependent regolith therm...
