Package index • mwi

The index

Compute the Mosquito Weather Index and its temperature-and-humidity-only variant.

mwi(): Mosquito Weather Index
mwi_fhft(): Temperature-and-humidity variant of the index (FHFT)

Response functions

The three weather responses the index is built from, and the wind cut-off they share.

mwi_temperature() mwi_humidity() mwi_wind(): Weather response functions
mwi_wind_threshold(): Wind cut-off used by the index

Aggregating over time

Summarise sub-daily weather into index values in the order the index requires.

mwi_summarise(): Summarise sub-daily weather into index values, in the correct order

Activity classes

Map continuous index values onto the five ordered classes used for public communication.

mwi_category(): Map index values onto the five activity classes
mwi_activity_levels(): Activity class labels

Unit conversions

Derive the index inputs from the forms in which reanalysis products distribute them.

relative_humidity_from_dewpoint(): Derive relative humidity from dewpoint and air temperature
wind_speed_from_components(): Wind speed from eastward and northward components
celsius_from_kelvin(): Convert Kelvin to degrees Celsius
