Urban-PLUMBER will evaluate the performance of land surface models used in in meteorological or climatic simulations of urban areas. The project is open to any group that wishes to gain a better understanding of how their model performs in a wide range of urban environments.

Previous urban model evaluation projects have assessed how model complexity affects prediction of land-atmosphere energy exchange at two urban sites (Grimmond et al., 2010, 2011), and how coupled surface-atmosphere simulations differ from offline simulations (Steeneveld et al., 2017). In non-urban landscapes, the PLUMBER project introduced a framework for benchmarking models across many sites (Best et al., 2015).

Building on these methods, Urban-PLUMBER will ask:

  1. How have the last decade of model development affected performance?
  2. Where do different modelling approaches excel across the urbanised/vegetated continuum?
  3. How does more detailed morphology information affect model performance?
  4. Are models utilising available meteorological information effectively?

Scope

The project has two phases:

Who should get involved?

Modelling participants: Models able to predict neighbourhood-scale land-atmosphere radiant and turbulent heat exchanges from meteorological inputs. Both specialised urban land surface models and those without an explicit urban representation are invited. Read the modelling protocol for more information.

Observations participants: Local-scale urban flux tower observations are needed to both drive models and evaluate outputs. Read the observations requirements for more information

Those who provide modelling or observational data will be invited as authors on relevant papers.

Phase 2

Phase 2 of the project (beginning December 2020) will include a range of sites where appropriate urban flux tower observations are available.
