Hi all,

Pretty new to NetCDF and ECMWF data.

Just a quick (probably with an obvious answer) question: What do I do with 
negative values? For example, I am using aermr04, aermr05 and aermr06 (dust) 
data from ECMWF. I have noticed many negative values.
What do I do with these data? Shall I just treat them as zeros? I ask because I 
am calculating the concentrations using the following formula:

Many thanks,
Richard
