James, > The Dobson Unit is the most common unit for measuring ozone concentration. > > 1 Dobson Unit (DU) is defined to be 0.01 mm thickness at STP. > > 1 DU ~ 2.69E+20 molecules per square meter I've added the unit "dobson" (symbol "DU") to the UDUNITS-2 package that I hope to release relatively soon. If you want to add the unit to your existing UDUNITS package, then I suggest using the following entries dobson P (2.69e20/6.022e23) mole/meter2 DU S dobson Regards, Steve Emmerson Ticket Details =================== Ticket ID: XPL-147330 Department: Support UDUNITS Priority: Normal Status: Closed
