meteo: Meteorological Vietnamese Data

In choisy/imhen: Meteorological Data for Vietnam

Description

A dataset containing the meteorological data of Vietnam collected per month from 69 climatic stations, from January 1960 to December 2017. Two versions exist in this package, meteo_r is the tidy version of the raw data and meteo is the tidy, clean version of the raw data, with the temperatures were checked and adjusted if necessary. Additionnally, aggregates of these climatic variables by the province definition of the most recent period (starting in 2008) are avaiable from 2008 to 2017 in meteo_intagg_2008_2017.

Usage

meteo

meteo_r

meteo_intagg_2008_2017

Format

A data frame with 37,848 rows and 10 variables:

• year: year of collection

• month: month of collection (ordered factor)

• station or province: name of the climatic station (for meteo and meteo_r) or the province (for /code meteo_intagg_2008_2017)

• Ta: monthly average of the daily average temperatures (in centigrad)

• Tx: monthly average of the daily maximal temperatures (in centigrad)

• Tm: monthly average of the daily minimal temperatures (in centigrad)

• Rf: monthly cumulative rainfall (in mm)

• aH: monthly average of absolute humidity (in g/m3)

• rH: monthly average of relative humidity (in %)

• Sh: monthly cumulative number of hours of sunshine

Details

The variable station is a key shared with dataset stations. The variable province is a key shared with the most recent polygon definitions of the provinces of Vietnam gadmVN::gadm()$province. The aggregated data are generated by interpolation and aggregation weighted by the local population density, using the 2009 data from WorldPop. The method used is detailed here. Note that values of relative humidity calculated to be higher than 100 are set to 100 and that values of absolute and relative humidities as well as rainfall and hours of sunshine calculated to be negative are set to 0.
