Description
Hi there,
First, thank you for the excellent work behind Aurora!
I'm interested in running Aurora Air Pollution and have a question regarding constructing batches. In the tutorial for Aurora Air Pollution (https://microsoft.github.io/aurora/example_cams.html) the previous 12-hour analysis dataset is included in data array used in the batch. The Bodnar et al. (2025) paper states that for some pollutants, Aurora predicts a 24-hour difference (Section B7 in the supporting information). If I'm interested in generating surface PM2.5 forecasts, should the data array used in the batch include the previous 24-hours in order to initialize with the 24-hour difference?
Additionally, if I'm only interested in PM2.5, does Aurora require trace gas (NO, O3, CO, etc.) input from CAMS in order to work properly?
Thanks so much!

Research direction
Start with the Aurora Air Pollution tutorial at microsoft.github.io/aurora/example_cams.html and Section B7 of the Bodnar et al. (2025) supporting information. Confirm the required input window for surface PM2.5 forecasts and whether trace-gas CAMS inputs are required, then document the confirmed guidance in the relevant tutorial or documentation.
