Abstract

An evapotranspiration model, based on the FAO Penman-Monteith method, taking into account the surface temperature, has been developed and implemented in the ground temperature model of the CitySim software. A case study was conducted in a district of Geneva, Switzerland, which consists of 704 buildings and 714 ground surfaces, to understand the influence of evapotranspiration on the ground surface temperature and water requirement for the irrigation of these areas at urban scale. The simulations were conducted to investigate the cooling potential of green areas in present and future climate scenarios. To handle the large quantity of inputs needed by CitySim and the large amount of results produced, a PostgreSQL database and QuantumGIS software have been used for this case study.

Sea surface temperature

Sea surface temperature (SST), or ocean surface temperature, is the ocean temperature close to the surface. The exact meaning of surface varies according to the measurement method used, but it is between and below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass.

Evapotranspiration

Evapotranspiration (ET) is the combined processes by which water moves from the earth's surface into the atmosphere. It covers both water evaporation (movement of water to the air directly from soil, canopies, and water bodies) and transpiration (evaporation that occurs through the stomata, or openings, in plant leaves). Evapotranspiration is an important part of the local water cycle and climate, and measurement of it plays a key role in agricultural irrigation and water resource management.

Database

In computing, a database is an organized collection of data (also known as a data store) stored and accessed electronically through the use of a database management system. Small databases can be stored on a , while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance.
