Sequestration of nitrogen dioxide

Source: R/indicator_NO2.R
no2_seq.Rd

This indicator returns the amount of NO2 that is sequestered by urban green.

Usage

no2_seq(x, green_df = NULL)

Arguments

x

An 'sf' object with the urban model of your city and a 'land_use' column with categories of urban features.

green_df

A dataframe of categories that are considered as urban green with four columns:

  1. 'land_uses': Column with the function to be considered in the calculations corresponding to 'land_use' column in 'x'.

  2. 'no2_seq1': The low range of NO2 sequestration of each function (in ug/s/m2).

  3. 'no2_seq2': The high range of NO2 sequestration of each function (in ug/s/m2).

  4. 'pGreen': The proportion of green surface in each function (0:1). This is overriden by 'edible_are' when land_uses are community garden, commercial garden, rooftop garden and hydroponic rooftop.

If NULL, the 'city_land_uses' dataset is used.

Value

A numeric value with the total NO2 sequestration in the city (in grams/second).
