[GRASS-user] Lights at night data

Dear Grass users,

I was wondering whether you you have any suggestions on where to find
geospatialdata on lights at night. I have managed to find some the
excellent time series data available on the NOAA website:

http://ngdc.noaa.gov/dmsp/downloadV4composites.html

The dataset is available at a resolution of 1km, but I would be
interested in something at a higher resolution (possibly 100m) for the
Europe/ the UK. I would interested in either time series data or
shapshots taken over a certain period of time. Any help would be
greatly appreciated!

Best wishes,

Marco Girardello

for the Night on Earth images seen here,

there is:

I suspect you won't be able to find 100m resolution for that,
but if you have a local need you might be able to reconstruct
what they did with nighttime satellite images, but maybe you
need a wide cumulative exposure to make it work well.(?)
