JULES Science Meeting, June 2016

Information about the JULES Science Meeting held in June 2016, hosted by Lancaster University

The JULES Annual Science Meeting 2016 was held at Lancaster University on 28th and 29th June 2016. This was followed by the JULES short course, which included hands-on training course in the use of JULES.

This was a new venue for the meeting, with the aspiration that it would catalyse fresh links with the land surface community working at the Lancaster Environment Centre and CEH Lancaster, as well as providing an update on recent developments and applications of JULES.

Session 1 - Configurations and Overview

JULES Update Doug Clark
Tools for JULES Richard Gilham
MIPS and iLAMB Chris Jones
The JULES Earth System Configuration for UKESM Anna Harper
Towards a universal model for ecosystem - atmosphere carbon and water exchanges Colin Prentice

Session 2 - Vegetation and Disturbance

Biophysical homoestasis of leaf temperature: a neglected process for vegetation and land surface  Ning Dong
INFERNO, an interactive fire and emission scheme now integrated in JULES Stephane Mangeon
Plant productivity response to diffuse radiation changes caused by secondary organic aerosol Alex Rap
Disturbance, mortality and turnover in global vegetation modelling Tom Pugh

Session 3 - Crops and Ecosystem Strategies

Recent developments in JULES crop Karina Williams
Quantifying the impact of ozone on crops productivity at regional scale using JULES-crop Felix Leung
European carbon sink strength reduced by plant ozone damage Rebecca Oliver

Results from the first year of leaf/twig trait observations and ecosystem monitoring compared with site specific JULES runs at Mill Haft, the BIFoR experimental woodland in Staffordshire.

Detailed evaluation of high latitude carbon cycle processes in JULES Sarah Chadburn
Influence of chalk hydrology on land surface processes in the UK Mostaquimur Rahman
The impact of high resolution soil on surface fluxes in JULES Heather Ashton

Session 5 - Application of JULES

What JULES can tell us about change in the Horn of Africa bimodal rainfall region in 2014 Toby Marthews
The current and future water balance of West-Africa with focus on Northern Ghana and Burkina Faso Peter Cook
Deposition: Linking the land surface and atmospheric composition Garry Hayman
Smart data assimilation with JULES in EMPIRE Sanita Vetra-Carvalho


JULES Short Course

As promised, we also held a short, hands-on training course in the use of JULES directly following the Annual Science Meeting. The course was led by Toby Marthews and included instructions from JULES users at both the Met Office and CEH. The course was aimed at all existing or potential users of JULES and provided a general guide to compiling and running the stand-alone version of the model, including explanation of the resources needed and how to interpret the output, and an overview of JULES development and version control. There was also a workshop component giving participants an opportunity to run the model themselves, following tutorial examples at their own pace, under the guidance of demonstrators. Please see here for an outline of the schedule.
The following presentations were presented:

Introduction to JULES - Garry Hayman

Resources for JULES - Heather Ashton & Kerry Smout-Day

Interpreting JULES Output - Emma Robinson

Basics of JULES Development - Richard Gilham
