The reconstruction adopts an ordinal scale index approach ranging from 2 (very cold) to 1 (warm). Based on the grading criteria, a total of 12,871 records were retrieved through a standard coding system established at REACHES. Sensitivity experiments were performed to test robustness of the index system and a reasonability test was conducted to develop an appropriate method for deriving areal mean temperature index. The reconstructed series were validated through comparison with early instrumental data from Global Historical Climatology Network which shows good correlations and reliability of the REACHES reconstructed index data. Annual and semi-annual (winter and summer) temperature index data series were released for the whole domain as well as the 3- and 15-subregion geographical domains in China.","pubRank":"1"}],"site":[{"NOAASiteId":"57703","siteName":"Mainland China","siteCode":null,"mappable":"N","locationName":"Continent>Asia>Eastern Asia>China","geo":{"geoType":"Feature","geometry":{"type":"POLYGON","coordinates":["18","53","73.5","134.5"]},"properties":{"southernmostLatitude":"18","northernmostLatitude":"53","westernmostLongitude":"73.5","easternmostLongitude":"134.5","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"reaches_record_density","NOAADataTableId":"51900","earliestYear":1368,"mostRecentYear":1911,"timeUnit":"CE","earliestYearBP":582,"mostRecentYearBP":39,"earliestYearCE":1368,"mostRecentYearCE":1911,"coreLengthMeters":null,"dataTableNotes":"This dataset is associated with the num_temp_records dataset.","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/historical/asia/china/reaches/wang2023-reaches_record_density.txt","urlDescription":"NOAA Template File","linkText":"Record Density Data","variables":[],"NOAAKeywords":["earth science>paleoclimate>historical"]}]},{"dataTableName":"reaches_spatialpolygon","NOAADataTableId":"51902","earliestYear":null,"mostRecentYear":null,"timeUnit":null,"earliestYearBP":null,"mostRecentYearBP":null,"earliestYearCE":null,"mostRecentYearCE":null,"coreLengthMeters":null,"dataTableNotes":"ZIP file.","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/historical/asia/china/reaches/wang2023-reaches_spatialpolygon.zip","urlDescription":"Zip File","linkText":"Shapefile - China Sub Regions","variables":[],"NOAAKeywords":["earth science>paleoclimate>historical"]}]},{"dataTableName":"reaches_num_temp_records","NOAADataTableId":"51901","earliestYear":1368,"mostRecentYear":1911,"timeUnit":"CE","earliestYearBP":582,"mostRecentYearBP":39,"earliestYearCE":1368,"mostRecentYearCE":1911,"coreLengthMeters":null,"dataTableNotes":"This dataset is associated with the record_density dataset.","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/historical/asia/china/reaches/wang2023-reaches_num_temp_records.txt","urlDescription":"NOAA Template File","linkText":"Number of Temperature Records in Region Data","variables":[],"NOAAKeywords":["earth science>paleoclimate>historical"]}]},{"dataTableName":"reaches_summer_temp","NOAADataTableId":"50367","earliestYear":1368,"mostRecentYear":1911,"timeUnit":"CE","earliestYearBP":582,"mostRecentYearBP":39,"earliestYearCE":1368,"mostRecentYearCE":1911,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/historical/asia/china/reaches/wang2023-reaches_summer_temp.txt","urlDescription":"NOAA Template File","linkText":"Summer Reconstructed Temperature Index Data","variables":[{"cvDataType":"CLIMATE RECONSTRUCTIONS|HISTORICAL","cvWhat":"earth system variable>temperature variable>temperature index","cvMaterial":null,"cvError":null,"cvUnit":"dimensionless","cvSeasonality":"5-month period>May-Sep","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"Areal Mean of Subregion in South China;
