goesaodc_listScanFiles: List GOES AOD scan files

In MazamaScience/MazamaSatelliteUtils: Utilities for Working with Model and Satellite Data as Rasters

Description

Lists GOES AOD scan files for a given datetime or time range. If just datetime is given, then only the scan file closest to that time will be listed. If endtime is specified as well, then all scans from datetime up to (but not including) endtime will be listed.

Usage

goesaodc_listScanFiles(
  satID = NULL,
  datetime = NULL,
  endtime = NULL,
  timezone = "UTC",
  isJulian = FALSE,
  useRemote = FALSE,
  baseUrl = "https://tools-1.airfire.org/Satellite/"
)

Arguments

satID	ID of the source GOES satellite ('G16' or 'G17').
datetime	Datetime as a Ymd HMS or Julian formatted string, or a POSIXct.
endtime	End time as a Ymd HMS or Julian formatted string, or a POSIXct.
timezone	Timezone used to interpret datetime and endtime. Defaults to UTC.
isJulian	Logical value determining whether datetime (and optionally endtime) should be interpreted as a Julian date with day of year as a decimal number. Defaults to FALSE.
useRemote	Logical specifying whether to look for files in getSatelliteDataDir() or baseUrl. Defaults to FALSE.
baseUrl	URL of remote database. Defaults to "https://tools-1.airfire.org/Satellite/".

Details

If useRemote=FALSE and there are no scan files available for the day of the requested datetime, then NULL will be returned.

Value

Vector of scan filenames.

Examples

library(MazamaSatelliteUtils)
setSatelliteDataDir("~/Data/Satellite")

goesaodc_listScanFiles(
  satID = "G17",
  datetime = "2020-09-08 12:30",
  timezone = "UTC",
  useRemote = TRUE
)

goesaodc_listScanFiles(
  satID = "G17",
  datetime = "2020-09-08 12:00",
  endtime = "2020-09-08 13:00",
  timezone = "UTC",
  useRemote = TRUE
