Get one day of Iowa Environmental Mesonet observations — iem

Retrieves one local calendar day of observations for one IEM station.

Usage

iem_obhistory(station, network, date = Sys.Date(), full = FALSE)

Arguments

station: A single station identifier, such as "DSM".
network: A single IEM network identifier, such as "IA_ASOS".
date: A single local calendar date as a Date object or YYYY-MM-DD string. Defaults to Sys.Date().
full: Logical. If TRUE, request all available observation fields.

Value

A tibble containing one day of station observations returned by IEM, with station identifiers in station_id when returned. Units and available variables vary by network.

Details

The date argument is interpreted by IEM as a local station calendar date. UTC timestamps are parsed as POSIXct values in the UTC time zone. Local timestamp fields are returned as character values because station time zones vary by network.
