#329 | fixed | Bias of footprint dependant on particle number | cluekenwinkels | |
Description |
Hello, I currently use FLEXPART-WRF in an urban setting on roughly 1 km resolution. In a test for the statistical error due to the limited particle number, I found not only statistical, but systematic differences (bias) between runs with different particle numbers. In particular, the sum of the footprints entries grows with the particle number. As I understand it the footprints' values should not generally grow with larger partical numbers, but become more and more consistent, which is not the case here. The same footprint was calculated for 10, 50, 250, and 500 thousand particles with very different results for the same release location, time and meteorology. The lowest paritcle number is chosen due to the vaule in reviewed papers using FLEXPART-WRF in an urban/meso scale setting:

#320 | fixed | Backward trajectory of PM | ashalsabila | |
Description |
I plan to do backward trajectory of particulate matter with different diameter (PM10, PM2,5, PM1, and PM0,1) with no information about it's chemical composition, is it possible? |
