Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production
PLANTS, PEOPLE, PLANET, EarlyView.Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Ultra Wide Swath Sea interferometric multibeam echo sounder with sea bottom imaging system.
, 1990 The SIMRAD EM12 is a new full ocean depth multibeam echo sounder, operating at 13 kHz. By use of interferometric signal processing techniques it will achieve an ultra wide swath geometry of 150 degrees, corresponding to 7.5 times the depth of water.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Assimilation of AMSU‐A all‐sky observations can be increased up to fivefold if spatial observation‐error correlations are accounted for properly. New correlation estimates derived using data from ECMWF and the UK Met Office reveal that correlation length‐scales are between 75 and 150 km for AMSU‐A channels peaking in the troposphere. This is attributed

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Using microwave imager observations to improve the ocean temperature in a coupled NWP system
Quarterly Journal of the Royal Meteorological Society, EarlyView.A recent upgrade to the ECMWF IFS has implemented outer‐loop coupling between the atmosphere and the ocean. This work uses this method to pass ocean skin temperature estimates derived from satellite‐borne microwave imagers to the ocean data assimilation system; the updated ocean state is then passed back to the atmospheric system.

First Processing of the Complete Sentinel-1 SAR Archive: 10 Years of Global Sea State
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingIn this study, the sea state was estimated and analyzed by processing the ten-year worldwide Sentinel-1 synthetic aperture radar (SAR) archive 2014−2024. The approx. 15 Petabytes of data contain approx. 4.2 million SAR scenes, where approx.

Coupled observation‐operator approximations in outer‐loop coupling data assimilation
Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action
