Joint Workshop on Representation Uncertainty in the Earth sciences: POSTPONED

Given the fact that the coronavirus situation is developing rapidly, and that the workshop is primarily discussion-based, we have decided to reschedule the workshop to December this year. We will send out further information regarding the rescheduled meeting in the near future. We apologise for any inconvenience caused and we hope that you are able to join us for the meeting later in the year.

Joint workshop on representation uncertainty in the Earth Sciences

When analysing data in the Earth Sciences it is often necessary to compare an observation of a physical quantity with its representation in a different form. This includes, for example, using an alternative observation of the same quantity; computing the equivalent of the observation in a geophysical model, which could include variable transformations; or by interpolating the observation onto a binned domain. Such processes result in a representation uncertainty, which is distinct from the instrumental uncertainty inherent in the observation, and is often difficult to evaluate.

Sponsored by the National Centre for Earth Observation, the objective of this workshop is to determine how representation uncertainty is defined and quantified in the Earth science communities of data assimilation, Earth observation and forecast verification. The workshop will facilitate discussion between experts in these communities and aims to develop a consistent terminology across fields, identify common goals and techniques, and foster future collaborations.

Registration and abstract submission

This one and a half day discussion based workshop is open to all experts in the associated fields. We anticipate a maximum of around 60 participants; please note, if the event is heavily over subscribed we may need to limit participation.

For the workshop we are soliciting abstracts for oral (15 minutes + 5 minutes for questions) and poster presentations. If you would like to apply to present, please submit your abstract using the registration form. Please note that this is an interactive workshop and not a conference so there are limited opportunities to present your work orally. We do encourage you to submit abstracts to present your work, but note that you may be assigned a poster rather than an oral presentation.

Key dates

14th February 2020: assignment of oral presentation/poster.
