Data for: Observations on dew formation in the rice canopy and its simulation using a multilayer microclimate model
Description
This dataset is the original data of the observation and simulation on dew formation conducted in the paper “Observations on dew formation in the rice canopy and its simulation using a multilayer microclimate model”. https://doi.org/10.2480/agrmet.D-22-00016 The dataset includes the vertical profile of the dew amount in the rice canopy measured at 0.2 m intervals, the plant area index (PAI) of each layer, meteorological factors and water temperature in a paddy field, and output of the multilayer microclimate model including simulated dew amount. Observations were conducted in 2003 in a paddy field located in Kumamoto, Japan. The vertical profile of the dew amount was observed on four nights‑three nights at the booting period and one at the grain filling period. PAI of each layer was measured at the booting and grain filling periods. Meteorological factors and water temperature were observed for use as boundary conditions in the multilayer microclimate model. Output of the multilayer microclimate model include the atmospheric condition and energy balance at each layer in the canopy. Other details are described in the paper. Symbols in the dataset in each file denote the following variables. --- Observation.csv --- LAI: Leaf area index (m2/m2) HAI: Panicle area index (m2/m2) SAI: Stem area index (m2/m2) PAI: Plant area index (m2/m2); PAI=LAI+HAI+SAI Dew: Dew amount on the leaf/panicle (mm: per unit hemi-surface area) DewTotal: Total dew amount on each layer (mm: per unit land surface area) --- Simulation.csv --- The time stamp means the average value of the previous 30 minutes. (For example, 02:00 means the average value from 01:30 to 02:00) --- Input variables (observed value) --- Ta: Air temperature at reference height of 2m (°C) qa: Specific humidity at reference height of 2m (g/kg) U: Wind speed at reference height of 2m (m/s) Sd: Downward solar radiation above the canopy (W/m2) Ld: Downward longwave radiation solar radiation above the canopy (W/m2) Tw: Water temperature at the center of the field (°C) --- Output variables at each layer in the canopy --- T(z): Air temperature (°C) RH(z): Relative humidity (%) Tc(z): Leaf temperature (°C) Rn(z): Net radiation on the leaf (W/m2) LE(z): Latent heat flux on the leaf (W/m2) Dew(z): Dew amount on the leaf (mm: per unit hemi-surface area) DewTotal: Total dew amount on the canopy (mm: per unit land surface area) (z=1: 0.0-0.2m, z=2: 0.2-0.4m, z=3: 0.4-0.6m, z=4: 0.6-0.8m, z=5: 0.8-1.0m)
