Is BfastSpatial applicable to climate data?

Open Jacksonmrodrigues opened this issue 5 years ago • 2 comments

Hi Loïc ,

Is there any restriction or recommendation in using BfastSpatial functions (breaking points detections, trends and others) on climate time series (temperature, precipitation)?

Do I have to care about seasonality or something else? I could not find such of info.

Best

Hi Jackson, Absolutely, structural change detection is not limited to vegetation index time series. See the example from strucchange::efp (that bfastmonitor uses internally) for instance on riverflow or mortality data. Precipitation is temporally discrete though, so you would have to process it into a meaningful temporally continuous variable.

Hi Loïc,, Thank you for replying! I have netcdf datasets of several climate variables (raster bricks). I would like to test for breaking points detections and trends. Next step is to compare packages greenbrown, bfastspatial and bfast.

I will certainly annoy you and others within next days for a better comprehension of some precedures and commands.

Thank you very much again.

Great job with this package!

Jackson
