chicagoNMMAPS: Daily Mortality Weather and Pollution Data for Chicago

In gasparrini/dlnm: Distributed Lag Non-Linear Models

Description

The data set contains daily mortality (all causes, CVD, respiratory), weather (temperature, dew point temperature, relative humidity) and pollution data (PM10 and ozone) for Chicago in the period 1987-2000 from the National Morbidity, Mortality and Air Pollution Study (NMMAPS)

Usage

Format

A data frame with 5114 observations on the following 14 variables.

• date: Date in the period 1987-2000.

• time: The sequence of observations

• year: Year

• month: Month (numeric)

• doy: Day of the year

• dow: Day of the week (factor)

• death: Counts of all cause mortality excluding accident

• cvd: Cardiovascular Deaths

• resp: Respiratory Deaths

• temp: Mean temperature (in Celsius degrees)

• dptp: Dew point temperature

• rhum: Mean relative humidity

• pm10: PM10

• o3: Ozone

Details

These data represents a subsample of the variables included in the NMMAPS dataset for Chicago.

The variable temp is derived from the original tmpd after a transformation from Fahrenheit to Celsius. The variables pm10 and o3 are an approximated reconstruction of the original series, adding the de-trended values and the median of the long term trend. This is the reason they include negative values.

Source

The complete dataset used to be available at the Internet-based Health and Air Pollution Surveillance System (iHAPSS) website, or through the packages NMMAPSdata or NMMAPSlite. Currently, the data are not available any more and the two packages have been archived.
