Abstract

The New York State Mesonet (NYSM) was established in 2014 to provide high-quality real-time meteorological data for weather monitoring and forecasting, emergency management, and research aimed at improving numerical weather prediction. The mainstay of the network consists of 126 surface weather stations located throughout New York State with an average spacing of 30 km. In 2017, 17 of the sites (“flux” sites) were equipped with additional (permanent) instrumentation to measure short and long-wave radiation components, soil heat flux, and turbulent fluxes of momentum, sensible and latent heat, and carbon dioxide (CO2). The mesoscale resolution of the 17-site NYSM Flux Tower Network is distinctive among existing flux tower networks. The data have potential to improve surface parameterizations in numerical weather models as well as to address many research questions related to the surface energy and carbon budgets, ecosystems and agriculture, hydrology, and surface layer exchange processes. This thesis presents site selection, instrumentation, data acquisition, flux computations, quality control, and operation protocols of the NYSM Flux Tower Network. Data from the first two years of operation are used to evaluate the land cover representation of measured fluxes, examine spatial and temporal variability of surface fluxes and CO2 concentration, and assess surface energy budget closure.
