Homogenisation of temperature data

Posted on March 11, 2022 by Clive Best

How accurate is the pair-wise homogenisation algorithm applied to GHCN land temperature measurements and the instrumentation corrections made to sea surface temperatures? Long term station measurements are affected  by a station’s physical relocation, by environmental changes (urban development)  and by … Continue reading →
