title: diFUME In-situ meteorological dataset

description: Description


Air temperature and vapor pressure are measured on a micrometeorological tower located near the centre of Basel (BKLI). Vapor Pressure Deficit (VPD) is then calculated based on saturated vapor pressure estimation. Direct and diffuse incoming radiation are measured with a 2-axis sun tracker (INTRA, BRUSAG) at the roof-level in an unobscured location next to the micrometeorological tower. Measured shortwave radiant flux densities (W m-2) are converted to photon flux densities (μmol m-2 s-1) within PAR (i.e. photosynthetic active radiation, solar shortwave radiation between 400 – 700 nm) using a standard conversion factor. Soil temperature (oC) and volumetric water content (m3 m-3) are continuously measured at three different locations of the study area at 10 cm below surface. The locations have different characteristics, BKLI is at a street canyon, BKFP is at a non-irrigated park location and BSMP is at an irrigated park location. Soil temperature is also continuously measured at a station outside the city center (BLER) and soil volumetric water content is estimated from lysimeter measurements from another station outside the city centre (BIN).
