Abstract: Kriging, an interpolation procedure that minimizes interpolation error and gives an accurate estimate of that error, is shown to be an appropriate objective analysis procedure for the study of spatial variability and ...

Abstract: The American Society for Testing and Materials (ASTM) has proposed a standard method for testing the performance characteristics of a wind vane. This paper presents the procedures used to test and evaluate the ASTM method, ...

Abstract: A detailed, long term portrait of the seasonality of precipitation over the United States is developed using a 90 year climate division record. Selected decadal maps of seasonality are also presented, and their variability ...

Abstract: Using data complied from seven nationwide precipitation chemistry networks in the United States and Canada, the spatial distribution of hydrogen, sulfate and nitrate ions in North America is discussed. Geographic patterns ...

Abstract: The conditional sampling flux measurement technique was evaluated for four scalars (temperature, water vapor, ozone, and carbon dioxide) by comparison with direct eddy correlation measurements at two sites. The empirical ...
