Artificial intelligence reconstructs missing climate information

Abstract

Historical temperature measurements are the basis of global climate datasets like HadCRUT4. 

This dataset contains many missing values, particularly for periods before the mid-twentieth century, although recent years are also incomplete.

评论:我觉得有问题。

Here we demonstrate that artificial intelligence can skilfully fill these observational gaps when combined with numerical climate model data

评论:US English uses “skillfully.” I am losing this battle, but as long as I can manage, I will use “model outputs.”

We show that recently developed image inpainting techniques perform accurate monthly reconstructions via transfer learning using either 20CR (Twentieth-Century Reanalysis) or the CMIP5 (Coupled Model Intercomparison Project Phase 5) experiments. 

评论:People or animals perform, techniques do NOT.

The resulting global annual mean temperature time series exhibit high Pearson correlation coefficients (≥0.9941) and low root mean squared errors (≤0.0547 °C) as compared with the original data. 

These techniques also provide advantages relative to state-of-the-art kriging interpolation and principal component analysis-based infilling. 

When applied to HadCRUT4, our method restores a missing spatial pattern of the documented El Niño from July 1877. 

With respect to the global mean temperature time series, a HadCRUT4 reconstruction by our method points to a cooler nineteenth century, a less apparent hiatus in the twenty-first century, an even warmer 2016 being the warmest year on record and a stronger global trend between 1850 and 2018 relative to previous estimates. 

评论:Too long a sentence.

We propose image inpainting as an approach to reconstruct missing climate information and thereby reduce uncertainties and biases in climate records.

评论:Use “to reduce.”
