| Description | PAGODA - studying the role of evaporation in the global water cycle. We have studied the way that different components of evaporation have different time-signals: interception is faster than transpiration. We have developed code to distinguish between these two evaporative routes using flux data. The size of store is the key factor as well as the aerodynamic resistance. The data may be used to identify interception stores. New methods to validate the evaporation in JULES have been developed using a simple climate-informed water-balance model. This provides a background to the most parsimonious evaporation model against which model performance can be evaluated. |
| Exploitation Route | Using the new data, we will be able to improve the representation of interception in JULES, a key component of the weather forecasting and climate prediction suite at the UK Met Office. evaluating global evaporation is a key factor in improving model performance. |
