Questions/Comments • Has data changed recently?

Hi everyone.

I am back on a project I left in October 2023. This project involve extracting MODIS PAR data at several locations inside this bbox:

xmin ymin xmax ymax
-95.53711 57.65716 -58.71094 71.82884

As of today, I found out that the filenames to access the data has changed. For example, to download MONTHLY PAR of March-2003:

- Filename I was using in last October: A20030602003090.L3m_MO_PAR_par_4km.nc
- Filename as of today: AQUA_MODIS.20030301_20030331.L3m.MO.PAR.par.4km.nc

So I changed my code to adopt the new file naming convention.

However, I have noticed that the data also changed. On the attached plot, the top panel shows the data as it was in the file downloaded in October 2023, the bottom panel shows the data downloaded today (the circles represent the buffers in which I am extracting data).

Is it possible that the data have changed recently?

Thank you,
Phil
