Hi everyone,
Please, how can I obtain time series data by country on night-time light (brightness) ?
I've tried, but so far all I can find are maps. I am looking for numerical data, especially in excel format in order to complete my panel database.
In fact, I would like to approximate the GDP of each country rather by night-time light, as suggested by Henderson et al (2012) ["Measuring Economic Growth from Outer Space", Vol. 102, No. 2, The American Economic Review ].
Thank you!
