Why is NASA the official keeper of the temperature?

NASA Goddard Institute for Space Studies offers data,
as do several other organizations. I use NASA's data
because GISS corrects for UHI using nighttime earth
shine, artificial lighting, measured from satellites.
IMHO, this method is better than using census data
to locate urban areas.
