Marine heatwaves and cold spells events based on ESA-CCI SSTs (experimental product)

This repository contains an extension of the catalogues of marine heatwaves (MHWs) and cold spells (MCSs) prepared by the National Research Council - Institute of Marine Sciences (CNR-ISMAR, Italy) within the ESA-funded CAREHeat project. The catalogues are based on the ESA-CCI sea surface temperature (SST) dataset (available from https://doi.org/10.24381/cds.cf608234) for the period 1982-2022, on a regular 1°x1° longitude-latitude grid. Events are identified for each pixel following the methodology of Hobday et al. (2016) after preprocessing. Event categories are provided as daily maps and metrics are given by event. Results are experimental since the post-processing procedure effectively removes interannual variability from the SST record, so please use having consulted the documentation and not for operational purposes. Please cite the reference paper "Serva, F., et al.: Detection of Satellite Sea Surface Temperature Extremes: Low Frequency Variability and Climate Change, JGR:Oceans, 10.1029/2025JC022886, 2025" when using the dataset in your work.本仓库包含由意大利国家研究委员会海洋科学研究所（CNR-ISMAR）在欧洲空间局（ESA）资助的CAREHeat项目框架下编制的海洋热浪（MHWs）与海洋冷事件（MCSs）编目的扩展版本。 该编目基于1982-2022年时段的欧洲空间局气候变化倡议海表温度（ESA-CCI SST）数据集（获取链接：https://doi.org/10.24381/cds.cf608234），空间分辨率为规则1°×1°经纬度网格。 经预处理后，本数据集按照Hobday等人2016年提出的方法体系对每个像元的极端事件进行识别。事件类别以每日分布图形式提供，单事件统计指标则按事件逐一给出。由于后处理流程已有效去除海表温度序列中的年际变率，本数据集成果仍处于试验阶段，因此请在查阅配套文档后使用，且请勿将其用于业务化应用场景。 若在研究工作中使用本数据集，请引用以下文献：Serva, F. 等：《卫星海表温度极端事件检测：低频变率与气候变化》，《地球物理学研究杂志：海洋（JGR:Oceans）》，10.1029/2025JC022886，2025年。
