A linked panel dataset of daily tourism arrivals, sectoral spending, local-unit consumption, and extreme-weather indicators for Jeju Island, South Korea (2019–2025)

This dataset integrates four thematically related but institutionally dispersed data sources for Jeju Island, South Korea, covering January 2019 to September 2025. The dataset was compiled to support a multiscalar analysis of how extreme weather affects tourism arrivals, sectoral spending composition, and local spatial consumption patterns.
File 1 - Daily tourism arrivals (2,465 observations): Daily visitor counts disaggregated by domestic and international visitors, compiled from the Jeju Tourism Association. Seven dates record zero arrivals corresponding to weather-induced complete gateway suspension.
File 2 - Sectoral tourism spending (486 sector-month observations): Monthly tourism spending across six sectors (retail, transport, food services, accommodation, arts/sports/leisure, and other services) sourced from the Korea Tourism Organization Datalab (datalab.visitkorea.or.kr), based on Shinhan Card transaction records.
File 3 - Local-unit tourism spending (43 administrative units x 81 months): Monthly tourism spending for 43 sub-municipal administrative units across Jeju-si and Seogwipo-si, sourced from the Jeju Tourism Organization data platform (data.ijto.or.kr). Subsequent platform restructuring has restricted equivalent access to this historical series.
File 4 - Extreme-weather indicators: Daily binary indicators and monthly event-day counts for three extreme-weather types (heatwave 33°C or above, heavy rain 80mm or above, strong wind 14m/s or above) from four Korea Meteorological Administration ASOS stations (Jeju 184, Gosan 185, Seongsan 188, Seogwipo 189).
The dataset spans a pre-pandemic baseline (2019), COVID-19 disruption period (2020-2022), and post-recovery extreme-weather intensification (2023-2025).

本数据集整合了韩国济州岛主题相关但分属不同机构的四类数据源，时间跨度为2019年1月至2025年9月，旨在支撑多尺度分析极端天气对旅游到访量、行业支出结构及本地空间消费模式的影响。

文件1——每日旅游到访量（共2465条观测值）：由济州旅游协会汇编的分国内、国际游客的每日到访人数统计，其中7天的到访量为0，对应因天气导致的完全入境通道关停情况。

文件2——行业级旅游支出（共486条行业-月度观测值）：基于新韩卡（Shinhan Card）交易记录，由韩国旅游组织数据实验室（datalab.visitkorea.or.kr）汇编的六大行业月度旅游支出数据，涵盖零售、交通、餐饮服务、住宿、文体休闲及其他服务业。

文件3——本地单元旅游支出（43个行政单元×81个月）：由济州旅游组织数据平台（data.ijto.or.kr）提供的济州特别自治道济州市与西归浦市下辖43个次级行政单元的月度旅游支出数据。后续该平台进行了架构调整，限制了对该历史数据集的同等访问权限。

文件4——极端天气指标：包含三类极端天气类型（热浪：气温≥33℃；强降雨：日降水量≥80mm；强风：风速≥14m/s）的每日二分类指标及月度事件天数统计，数据取自韩国气象厅下属的4个自动地面观测站（Automated Surface Observing System，ASOS）：济州站（184）、孤山站（185）、城山站（188）、西归浦站（189）。

本数据集覆盖了新冠疫情前基准期（2019年）、新冠疫情冲击期（2020-2022年）以及疫后复苏阶段极端天气加剧期（2023-2025年）。
