Dr Anna E. Hogg
I am an Associate Professor in the School of Earth and Environment at the University of Leeds, working in the Institute for Atmospheric and Climate Science (ICAS), and am co-director of the NERC SENSE Earth Observation Centre for Doctoral Training (CDT). I was previously awarded a Natural Environment Research Council (NERC) Knowledge Exchange Independent Research Fellowship which was formally affiliated with the UK Satellite Applications Catapult, along with a European Space Agency (ESA) independent research fellowship at the University of Leeds which was co-sponsored by British Antarctic Survey (BAS). I conduct my research activities alongside my teaching responsibility at the University of Leeds.
My primary field of expertise is Earth Observation of the Polar regions, where over the past decade I have gained a detailed technical understanding of how to process a range of satellite data types (e.g. Synthetic Aperture Radar (SAR), and radar altimetry), from a large number of Earth Observation satellites (e.g. ERS-1/2, ENVISAT, TerraSAR-X, Sentinel-1, CryoSat-2), using multiple processing techniques (e.g. interferometry (InSAR), feature tracking). I have used satellite Earth Observation data to write journal papers on ice speed, grounding line location, ice elevation change, and calving front migration. I have broader previous experience of working with multispectral optical and polarimetric SAR data for terrestrial applications, such as land surface type classification and vegetation health. I am deeply connected to the international Earth Observation community, and through my role on the UK Space Agencies (UKSA) Earth Observation Advisory Committee (EOAC), I enjoy working with academics and space industry experts to identify scientific and industrial strategic goals that shape the future direction of our national Earth Observation capability.
I have broad experience of collaborative research, having managed or led over 10 international projects funded by ESA, and through my role as a member of NERC CPOM which has involved liaising with the NERC Ice Sheet Stability Research (iSTAR) program and the NERC Ocean Regulation of Climate by Heat and Carbon Sequestration and Transport (Orchestra) program. I am passionate about the translation of fundamental environmental science to generate socio-economic benefits by exploring non-commercial applications for Earth Observation datasets; such as by developing the world’s first Near Real Time (NRT) ice velocity monitoring service, and supervising the development of the world’s first sea ice thickness mobile phone application.
I deliver NERC national capability by developing and running the worlds first Near Real Time (NRT) ice velocity monitoring service. Through this data portal, we distribute frequent maps of ice velocity for six key outlet glaciers of the Antarctic and Greenland ice sheets in near real time, including Pine Island, Thwaites, Brunt, Petermann, Jackobshavn Isbrae and 79 Fjorden Glaciers. The velocity maps are produced by tracking moving features in synthetic aperture radar data acquired by the European Space Agency’s Sentinel-1 satellite.
I also developed a data portal for monitoring ice shelves in Antarctica. Check out this link to discover how the Brunt Ice Shelf is changing!
Scientific Research Projects
I have managed, led or worked on 17 international research projects funded by ESA, NERC, UKSA & NASA; collaborated with international project partners from 35 institutions in 11 countries including: USA, Germany, France, Italy, Austria, Denmark, Netherlands, Spain, Switzerland, Norway, Finland and the UK. As an independent scientist I have successfully won funding on 12 grant applications, returning over £4.9 mill to the University of Leeds.

I have participated in five major field campaigns on the Antarctic and Greenland Ice Sheets, ranging in duration from 4 months to 2 weeks. This includes the first NERC Ice Sheet Stability (iSTAR) traverse of Pine Island Glacier, West Antarctica, 3 ESA-NERC CryoVex/KAREN land ice campaigns on the EGIG line of the Greenland Ice Sheet, and an ESA-NERC CryoVex/KAREN land ice campaign in Western Palmer Land on the Antarctic Peninsula. I have designed and conducted experiments using a Ku-band radar (pRES), Ground Penetrating Radar (GPR), and ice coring.

Media and Science Communication
As a member of the EO science community, I believe it is important to publicly communicate the benefits of satellite data through news and media outlets whenever the opportunity arises. I regularly provide comments for national and international:
- Newspaper article lead author: The Guardian
- Newspaper article comments: The Guardian, The Independent, BBC News Online, The Mail Online, CNN, Business Insider, Fox News, Huffington Post, Time, International Business Times, Space Daily, etc.
- Radio interviews: BBC Weekend Weather Show, National Public Radio (NPR), BBC Gloucestershire, CBC News, Today FM, News talk ZB, Radio Sputnik, BBC Wales, Somerset Live, Ulster Live, Jersey Live, Shropshire Live, Scotland Live, Foyle Live, Cornwall Live, Wales Live, Berkshire Live, Leicester Live, Wiltshire Live, Lincolnshire Live, Norfolk Live etc.
- TV interviews: BBC Breakfast Live, BBC World News Live, CBC News.
I am enthusiastic about making videos and animations to communicate how satellite data can be used to better understand the Polar regions. Examples of my animations which have been published on the ESA website, some of which have been viewed over 100,000 times, and are available to view and download from the links below:
