Good find Zack, I can ask ECMWF about it but I suspect it's some kind of interpolation error from MARS.
However, I wouldn't worry too much about it given the magnitude of the values -- even if you sum them all up, you'd get ~1E-7 which is -0.0001 mm, so I don't think setting them to 0 or not will change the results.
It appears there are lots of negative pixel values present in the ECMWF HRES rasters we currently have downloaded. Therefore, wondering if there is any info from ECMWF on this matter as negative precip forecast does not really make sense. The values tend to be quite small, but there are alot of them. Perhaps it makes sense to convert all negative values to 0? Any ideas @turnerm ?
