Sensible Heat Fluxes over an Urban Area—Vancouver, B.C. [PDF]

open access: yesJournal of Applied Meteorology, 1974
The use of the eddy correlation technique is demonstrated for the measurement of sensible heat transfer in an urban area. The problems of time and space sampling (in the horizontal and vertical) are investigated. Based on 27 summer days of observations from a roof-top site in the central built-up part of Vancouver, the diurnal variation of sensible ...

Measuring sensible heat flux with high spatial density [PDF]

open access: yes2012 IEEE Sensors Applications Symposium Proceedings, 2012
Sensible heat flux is an essential quantity in the surface energy budget. Information about it is crucial for the derivation of models of air-surface interaction which in turn are needed for larger scale climate models. Sensible heat flux varies greatly across short distances and thus many sensors are required in order to obtain measurements of ...

Estimation of evapotranspiration fluxes over mustard using a Two-Source Energy Balance model

open access: yesJournal of Water and Climate Change, 2023
A Two-Source Energy Balance (TSEB) model computes surface energy fluxes using soil surface temperature and canopy temperature. An experiment was carried out in a research farm near the agrometeorological observatory, at Anand, India to parameterize the ...

Dropsonde-Based Heat Fluxes and Mixed Layer Height over the Sea Surface near the Korean Peninsula

open access: yesRemote Sensing, 2022
Dropsonde-based sensible heat flux, latent heat flux, and buoyancy flux were estimated over the sea around the Korean Peninsula in 2021. During a preceding severe weather (SW) mission, a total of 243 dropsondes were released from a National Institute of ...
