Add your files
Upload the two files you selected on Zindi. Each team can upload once, and entries are final. Only the 192 values for 11-12 Nov (4 stations x 48 hours) are read from each file and stored. Nobody can see your predictions. The board shows only the better of your two scores.
How scoring works
- Truth: hourly PM2.5 from OpenAQ (data from CPCB / IITM monitors), fetched every hour.
- Only hours with at least 3 readings count, and each file's RMSE is pooled over all four stations. A team ranks by its better file, as on Zindi.
- This is not Zindi's official score. Zindi uses its own copy of the data and may count hours differently. Official results come from Zindi.
- Team names must match a name on the Zindi leaderboard (any capitalisation). Please upload only your own team's files.
