The suitability of routine weather data for estimating local estuarine heat energy fluxes

Abstract: Meteorological data and water temperatures from a 98-day period during the summer of 1980 are used to examine the suitability of routine weather observations for quantifying the heat energy budget of a shallow lagoon on the Atlantic coast of Florida. Hourly cloud-cover observations are used to calculate incoming solar radiation, and results are compared with pyranometer readings. The standard error of the estimate is 26% of the mean daily accumulation for simulations of one day, but this decreases to only 0.3% of the total accumulation for simulations of 21 days. Wind speeds recorded at a weather station 4 km from the study site must be modified by a site-specific wind ratio before they can be used to calculate latent and sensible heat fluxes. Even with site-specific corrections to routine weather data, the standard deviation of simulated temperatures is 2 to 3 times that of observed temperatures. Cloud cover and wind speed are the two variables most difficult to incorporate into the simulations.

Siteclimate: a program to create hourly site-specific weather data

Abstract: Building loads are calculated using hourly weather tapes from the nearest available first-order weather station, or from data summarized from such tapes These weather stations are ofter remote from the building site, and in different terrain The climate experienced on site may be significantly different from that on the weather tape, and as such a result the energy use simulated for envelope-dominated buildings can contain substantial error A program is described that modifies hourly weather tape data to make them more closely approximate the climate found on building sites The program is eventually intended to be used by designers, engineers and researchers, who will input both local climate data and a description of the building site's physical surrounding in order to make the data transformations The method is only partially tested and is still under development In this paper, the approach used to modify hourly weather data is discussed, the method of user input is presented, and the individual algorithms are summarized Future refinements to the program and validation studies are outlined
