A software package 1s to provide the eddy correlation community with a fast and efficient means to both preprocessing averaging and analyzing their eddy flux data SOHFEA is designed for both rapid field processing of data for a first look on data quality and fluxes as well as for final processing for publication level results SOHFEA is written in Fortran 90 and uses a Fortran digital compiler to ensure fast program execution times minutes for a 5 day long data set SOHFEA 1s free to the academic and scientific community and can be downloaded at http dfmcginnis com SOHPFEA This instruction manual assumes an introductory knowledge of the eddy correlation technique however some key references are provided The manual is geared towards but not limited to the GEOMAR eddy configuration McGinnis et al 2011 and the recommended eddy data collection settings continuous mode as opposed to burst at 64 Hz In my opinion these settings provide optimum flexibility for extracting high quality data Please send any comments feedback suggestions or bug reports to dfmcginnis yahoo com I would be happy to hear from you Acknowledgements I would like to express my thanks to Karl Attard and Kasper Hancke University of Southern Denmark and Andreas Lorke Uni Landau Koblenz for providing excellent feedback on SOHFEA and the manual and website Software Package Overview SOHFEA Ver 2 0 consists of three processing categories Pre
