Abstract Isotopic data provide powerful constraints on regional and global methane emissions their source profiles. However, inverse modeling of spatially resolved flux is currently constrained by a lack information the variability isotopic signatures. In this study, signatures in Fennoscandian Arctic have been determined chambers over wetland, air 0.3 to 3 m above wetland surface aircraft sampling from 100 wetlands up stratosphere. Overall, atmosphere has coherent δ 13 C signature −71 ± 1‰,...
Wind damage is an important driver of forest structure and dynamics, but it poorly understood in natural broadleaf forests. This paper presents a new approach the study wind damage: combining terrestrial laser scanning (TLS) data finite element analysis. Recent advances tree reconstruction from TLS allowed us to accurately represent 3D geometry mechanical simulation, without need for arduous manual mapping or simplifying assumptions about shape. We used this simulation predict strains...
Abstract. Interactions between wind and trees control energy exchanges the atmosphere forest canopies. This exchange can lead to widespread damage of trees, is a key disturbance agent in many world's forests. However, most research on this topic has focused conifer plantations, where risk management economically important, rather than broadleaf forests, which dominate carbon cycle. study brings together tree motion time-series data systematically evaluate factors influencing responses...
Abstract The Diabatic Influences on Mesoscale Structures in Extratropical Storms (DIAMET) project aims to improve forecasts of high-impact weather extratropical cyclones through field measurements, high-resolution numerical modeling, and improved design ensemble forecasting data assimilation systems. This article introduces DIAMET presents some the first results. Four campaigns were conducted by project, one which, late 2011, coincided with an exceptionally stormy period marked unusually...
Abstract The main field activities of the Coordinated Airborne Studies in Tropics (CAST) campaign took place west Pacific during January–February 2014. was based Guam (13.5°N, 144.8°E), using U.K. Facility for Atmospheric Measurements (FAAM) BAe-146 atmospheric research aircraft, and coordinated with Tropical Tropopause Experiment (ATTREX) project an unmanned Global Hawk Convective Transport Active Species (CONTRAST) a Gulfstream V aircraft. Together, three aircraft were able to make...
Abstract. An uncontrolled gas leak from 25 March to 16 May 2012 led evacuation of the Total Elgin wellhead and neighbouring drilling production platforms in UK North Sea. Initially atmospheric flow rate leaking condensate was very poorly known, hampering environmental assessment well control efforts. Six flights by FAAM chemically instrumented BAe-146 research aircraft were used quantify rate. The calculated assuming plume may be modelled a Gaussian distribution with two different solution...
Abstract Volcanoes are a key natural source of CO 2 , but global estimates volcanic flux predominantly based on measurements from fraction world's actively degassing volcanoes. We combine high‐precision airborne 2016 and 2017 with atmospheric dispersion modeling to quantify emissions Katla, major subglacial caldera in Iceland that last erupted 100 years ago has been undergoing significant unrest recent decades. Katla's sustained flux, 12–24 kt/d, is up an order magnitude greater than...

Simulations exhibit that...

Abstract. An uncontrolled gas leak from 25 March to 16 May 2012 led evacuation of the Total Elgin well head and neighbouring drilling production platforms in UK North Sea. Initially atmospheric flow rate leaking condensate was very poorly known, hampering environmental assessment control efforts. Six flights by FAAM chemically-instrumented BAe-146 research aircraft, were used quantify rate. Where appropriate, two different methods calculate rate: 1. Gaussian plume fitting vertical 2.

Far-Infrared up-welling radiance measurements over Greenland have yielded the first estimates of emissivity ice and snow in this spectral region. I describe complexity undertaking such work what future holds.
A computational fluid dynamics (CFD) investigation was aimed at accurately predicting the air flow characteristics in vicinity of underwing-mounted instruments on Facility for Airborne Atmospheric Measurement’s (FAAM) BAe-146-301. Perturbation free stream airflow as it passes through region detection underwing may lead to additional uncertainties measurement clouds and cloud particles.
