[GRASS-dev] r.series counting maps over certain threshold?

[Markus Neteler]

Hi

I need to calculate threshold value for growing degree days
http://en.wikipedia.org/wiki/Growing-degree_day

(we used that in our paper:

Neteler, M., Roiz, D., Rocchini, D., Castellani, C. and Rizzoli, A.
(2011). Terra and Aqua satellites track tiger mosquito invasion:
modeling the potential distribution of Aedes albopictus in
north-eastern Italy. International Journal of Health Geographics,
10:49
http://www.ij-healthgeographics.com/content/10/1/49
)

The existing implementation has been reverted last year, but how to
do that now? I have to find out at which DOY in a pixel a certain value
has been reached. Input are all single daily GDD maps of the year. So
far I used r.series with threshold and count.

Another usage scenario: count all days over a certain temperature pixelwise...
?
