Berkeley Earth Surface Temperature

Berkeley Earth is a Berkeley, California-based independent 501(c)(3) non-profit focused on land temperature data analysis for climate science. Berkeley Earth was founded in early 2010 (originally called the Berkeley Earth Surface Temperature project) to address the major concerns from outside the scientific community regarding global warming and the instrumental temperature record. The project's stated aim was a "transparent approach, based on data analysis." In February 2013, Berkeley Earth became an independent non-profit. In August 2013, Berkeley Earth was granted 501(c)(3) tax-exempt status by the US government. The primary product is air temperatures over land, but they also produce a global dataset resulting from a merge of their land data with HadSST.
