This dataset includes estimates of the atmospheric methane relative interpolar difference (rIPD) across the Last Glacial Maximum and Deglaciation. The rIPD was calculated using discrete, high-resolution methane measurements from the WAIS Divide, NEEM and GISP2 ice cores. Two independent IPD records...
