Dennis- I have attached the entire "qflux" subdirectory which was apparently missing from the atsee collection you have. This is Bob Beardsley's "air-sea toolbox" and includes the > "hfbulktc.m" routine you mentioned. I have also attached the > current version of "qflux.m" that includes the modifications I have made for the case of the EDWIN LINK. Notice, for example, that we exclude "long wave radiation" component in the EL9905 case because we do not even know the units that of the data being logged. We could guess that they are W/m^2 /1000 but chose to just leave it out. Since the long-wave radiation is generally positive during this cruise, including that component would increase the net heat flux even more than what we have reported. -JiM. <> <> Attachment Converted: "\\tech\user\sci1\attach\qfluxtar.Z" Attachment Converted: "\\tech\user\sci1\attach\qflux.m"
