Diane is a remote sensing scientist specialising in trace gas retrievals from satellite data, working as part of the UK’s National Centre for Earth Observation (NCEO). Her background is in physics, having completed an MSc. degree in Physics and Astrophysics at the University of Birmingham, before going on to complete a PhD within the Earth …
The unprecedented spatial resolution offered by Copernicus Sentinel-5P’s Tropomi instrument means that we can now better analyse the complex relationship between tropospheric ozone and climate.
The project aims at developing a new methodology for detecting anthropogenic carbon dioxide emission sources. CO2 data from OCO-2 and NO2, SO2 and CO data from Sentinel-5P are collocated. The plan is to analyze these data in synergy to better detect anthropogenic CO2 sources and plumes. In detail OCO-2 XCO2 data is deseasonalized and detrended, …
The project aims at developing a new global tropospheric ozone datasets form TROPOMI and OMI measurements. These data will be a valuable addition to the operational TROPOMI Tropospheric ozone column product by the convective cloud differential method, which will be available for tropics only. In addition, the multi-limb-instrument stratospheric ozone column dataset, compatible with nadir …
The project will investigate Northern Hemisphere methane (CH4) sources and their connection to the soil freezing and thawing at high latitudes. We will innovatively combine methods for monitoring of CH4 (methane) emissions in the Northern Hemisphere by applying both data from Earth Observing (EO) satellites and global atmospheric methane inversion model estimates. The EO data …
In current atmospheric trace gas retrieval schemes exploiting UV-vis sounder data, clouds are treated in a simplistic way ignoring 3D structures and cloud shadows. In this activity, the impact of such cloud effects on trace gas products is quantified, building on statistical analyses of cloud observational data and on 3D Monte Carlo radiative transfer simulations …
Andreas studied physics and mathematics at the Philipps University of Marburg, Germany from 2000 to 2009. In 2007 he obtained a diploma in mathematics with thesis “Construction of multiwavelets and applications for adaptive numerical methods”, and in 2009 a diploma in physics with thesis title “Spatially resolved Raman and photoluminescence spectroscopy”. From 2010 to 2015 …
The holistic understanding of the Earth’s water and energy cycle remains one of the grandchallenges that the international scientific community needs to address in the next decade.The Raincast project is a multi-platform and multi-sensor study to address the requirement from theresearch and operational communities for global precipitation measurements. Raincast aims atidentifying and consolidating the science …
Living Planet Fellowship research project carried out by Diane Knappett. Global distributions of the methane (CH4) column average and carbon monoxide (CO) total column are observable by satellite shortwave infrared (SWIR) spectrometers through detection of surface-reflected solar radiation. Observations by ENVISAT SCIAMACHY and GOSAT-TANSO have been exploited extensively to investigate biogenic, pyrogenic and anthropogenic sources …
Living Planet Fellowship research project carried out by Andreas Schneider. The role of atmospheric water vapour in the hydrological cycle, the atmospheric circulation, and the radiation and energy budgets is largely uncertain. Improving knowledge on these is one of the key challenges in atmospheric sciences and of great importance for projections of climate change. Measurements …
