Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment

Working Groups

Objective: Three LIAISE Working Groups were established after the field campaign in November, 2021. The goal of these groups is to provide a forum for exchanges on research advances within LIAISE.

Overview

Structure: Two co-chairs for each WG, one junior and one senior, to lead and organize each WG and each WG meeting

Composition: These working groups would be made up of participants across all the partners and at all levels (PhD, post-doc, PI).

Priorities: The WGs should consist of connected people across institutes (and countries) who have a common interest in part of the campaign (incorporating observations and models), so scientists at the working level are collaborating and not working in isolation.

Meeting frequency: Monthly WG meeting centered on the activities of one of the three themes. The meeting will be led by the co-chairs with results and discussions centered on that particular WG progress, issues, etc. Members of other WGs are encouraged to attend. WG meetings will tentatively be the last Thursday of each month: they will be centered on one of the three WG themes (with each specific theme repeating every three months: see the calendar for updates).

Calendar and Presentations

WG Meeting schedule. More dates will be added as planning proceeds. We will send a mail as a reminder (to all of the WG participants) approximately 2 weeks ahead of time with the hour and video conference link. The meetings are tentatively planned to last approximately one to one and-a-half hours.

Working Group Description

WG 1 : Surface processes
Lead: Oscar Hartogensis, Co-chair: Mary-Rose Mangan

Processes:
- General: Water, energy and carbon balances and related processes in the interaction between the surface and the atmosphere (ET as key process that integrates all 3 balances). Latent/sensible heat fluxes links to the Boundary layer meteorology (WG2). Soil moisture is included in the coupling with WG3.
- Scales: Heat, momentum, H2O and CO2 fluxes/exchanges and radiation composition (e.g SIF) from leaf to field to landscape scale
Sites:
- SEB data: 7 local sites, 9 stations
- Lake Ivars (link with WG1, WG3)
Methods:
- Measurements and atmospheric and hydrological model applications
- Leaf scale: Ecophysiology (H2O+CO2)
- Field scale: EC, SEB (H2O+CO2+energy), towers, DTS, scintillometers, soil moister and heat, drones (SIF, Ts)
- Landscape scale: Aircraft-based remote sensing data of (GLORI, HyPlant, SLAP, CzechGlobe) and satellite remote sensing products

WG 2: Meteorology
Lead: Daniel Martínez-Villagrasa, Belén Martí López

Processes:
- Vertical: ABL processes
- Horizontal: Mesoscale circulations related to wet-dry, topography, sea breeze interaction
- Fire, interactions with ABL (M. Castellnou)
Sites:
- In situ local scale: La Cendrosa, Els Plans, ABL soundings, UHF, UAV profiles (obs), Mollerussa UAVs
- In situ over domain: Turbulence and state variables from the ATR42 (obs)
- Combined: Lidar observations (LMD)
Methods:
- Observations
- Mesoscale IOP Case studies
- Mesoscale Model Intercomparison Project (M. A. Jiménez Cortés)
- LES
- Column modeling

WG 3: Regional hydrology
Lead: Martin Best, Jan Polcher, Co-chair: Julie Colligan

Processes:
- Irrigation & streamflow/discharge
- Reservoirs (and their regulation)
- Regional scale estimates of surface properties related to soil water
Sites:
- Ebro basin: linkages between reservoir storage, irrigation, river storage & routing/damns (canals?)
- Boldu (soil moisture network, irrigation amounts known, satellite retrieved irrigation timing/amounts (IRRIGATION+)
Methods:
- Offline LSM and hydrological model basin scale simulations using Spanish SAFRAN forcing dataset for 2021 and longer term
