Tindongo daily relative humidity from 1983 to 2016

README - Tindongo daily Relative Humidity dataset File name---------tindongo_daily_relative_humidity_1981_2026.xlsx Short description-----------------This file contains a daily time series of relative humidity for the Tindongo location. Data source-----------Source product: CHIRTS Daily - Climate Hazards Center InfraRed Temperature with Stations daily data productGoogle Earth Engine asset / collection ID: UCSB-CHG/CHIRTS/DAILYOnline source link: https://developers.google.com/earth-engine/datasets/catalog/UCSB-CHG_CHIRTS_DAILYReference citation / DOI: Verdin, A. et al.

Variable--------Workbook column: Relative Humidity (%)Source variable: Relative humidityEarth Engine band: relative_humidityUnit in this Excel file: Percent (%)Frequency: DailyCovered period in this file: 1983-01-01 to 2016-12-31Number of records: 12419 Aggregation / extraction status-------------------------------Daily relative humidity value as provided by the CHIRTS Daily product.No unit conversion was applied; values are kept in percent.The data are kept as a single time series with one value per day.The Excel file does not contain evidence of any additional post-processing beyond extraction, unit formatting/conversion where stated, and tabular export. Extraction method-----------------The data were extracted from Google Earth Engine, according to the project workflow.The project context indicates the use of WASCAL Easy Satellite Data Access and Analysis Tool (WESAT) (https://wesat.wascal.org) wrapping the Google Earth Engine API for extraction.Likely extraction workflow:1. Select the Google Earth Engine ImageCollection: UCSB-CHG/CHIRTS/DAILY.2. Filter the collection to the covered period: 1983-01-01 to 2016-12-31.3. Select the band: relative_humidity.4. Extract the value for the Tindongo location using the WASCAL Easy Satellite Data Access and Analysis Tool (WESAT) (https://wesat.wascal.org)/GEE spatial configuration.5. Export the resulting time series to Excel. Recommended reproducibility information to archive with this file-----------------------------------------------------------------Sheet name: DonnéesDate column: DateDate format used in the file: YYYY-MM-DDFirst date/month: 1983-01-01Last date/month: 2016-12-31Expected days in period: 12419; missing days: 0; duplicate dates: 0; missing values: 0.Minimum value: 7.0424Maximum value: 99.5217Mean value over the file period: 51.2976 Quality and interpretation notes--------------------------------CHIRTS relative humidity is a derived gridded climate variable, not a direct in-situ humidity measurement.CHIRTS Daily provides high-resolution daily Tmin/Tmax and derived variables including relative humidity; RH is calculated using CHIRTS daily temperature values and ERA5 hourly inputs.Values represent the source product grid cell or the spatial aggregation used during extraction, depending on the WASCAL Easy Satellite Data Access and Analysis Tool (WESAT) (https://wesat.wascal.org)/GEE configuration.Use caution when comparing gridded products with local observations, because station measurements and gridded model/reanalysis values can represent different spatial and temporal supports.
