cpcQueryDateRange: Access CPC Data for a Short Date Range

In jdossgollin/cpcRain: Manage data from the CPC Unified Gauge-Based Analysis of Global Daily Precipitation data set

Description

This function provides access to CPC data for a date range. This function is intended to be called directly. For each date in the date range, it downloads the raw files, reads them to an array, and deletes the raw files. By default it returns a tidy data.table, but it can also return a 3D array.

Usage

cpcQueryDateRange(start_date, end_date, tidy = TRUE)

Arguments

start_date	the first data to download. Must be a date object – see lubridate package for easy creation of date objects with the lubridate::ymd() function.
end_date	as with start_date, must be a date object.
tidy	if TRUE, the output data will be a tidy data.table with columns lon, lat, and prcp_mm. if FALSE, the output data will be a 3D array with indices [lon, lat, time]

Value

returns a list with two entries: download_success and precip_data. download_success is a data.frame with columns date and success, which define whether data was successfully downloaded for each date in the range seq(start_date, end_date, 1). precip_data is a 3D array if tidy is FALSE and a data.table if tidy is TRUE.
