Data reprojection

[a-laborie]

Hello and thank you for all the great work put into geemap.
I am trying to reproject some data from MODIS (MOD09G.061) in Canada to a regular grid, 0.25° in both latitude and longitude. I know of the reproject function, I use it this way:

image.reproject(crs='EPSG:4326', scale)

I struggle to understand the behavior of the scale parameter. Is it the scale expected in the new CRS? Also, what is the expected unit: meter, degree?

Thanks in advance
AL
