Thank you very much for concerning my problem.
1, Yes, I using annual mean PM2.5
2. I imported a 2-km grid for my domain. The column and row number are consistent with those in air quality file.
So far, I partly resolve the problem, but I don’t really understand why. The imported air quality file need to fill “QuarterlyMean” in Seasonal Metric instead of keep blank as I did before. This is consistent with metrics of EPA health Impact functions that I used in this study. And I got the reasonable spatial distribution of baseline PM2.5 in the domain. The imported file of PM2.5, and spatial distribution shown like this:
However, for PM10, even I fill “QuarterlyMean” or keep Blank in Seasonal Metric, the baseline map is still incorrectly plotted. For PM10, I used Wong et al. 2008 RR to import manually into health impact functions, and keep blank in seasonal metric. But the imported baseline PM10 is still incorrect like that.
Can you give me some ideas what happen with my data? Why when I only fill in Seasonal Metric column of baseline PM2.5 file, its plot become correct, but it didn’t happen same thing with PM10?
Thanks and best regards,
