goesaodc_createScanTibble: Create a tibble from a ncdf4 handle

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

Description

Creates a tibble from a netCDF file with columns: AOD, DQF, lon and lat.

Usage

goesaodc_createScanTibble(nc = NULL, bbox = bbox_CONUS, dqfLevel = 3)

Arguments

nc	ncdf4 handle or a list of handles.
bbox	Bounding box for the region of interest. All points outside of this area will be removed. Defaults to CONUS.
dqfLevel	Allowed data quality level. All readings with a DQF value above this level will have their AOD values set to NA. Must be either 0, 1, 2, or 3, with 0 being the highest quality. Defaults to 3.

Value

tibble with netCDF variables and associated locations.

Examples

# Tibble based on full extent of Gridfile
library(MazamaSatelliteUtils)

setSatelliteDataDir("~/Data/Satellite")

scanFile <- goesaodc_downloadScanFiles(
  satID = "G17", 
  datetime = "2019-10-27 10:00",
  timezone = "America/Los_Angeles" 
)

nc <- goesaodc_openScanFile(scanFile)

tbl <- goesaodc_createScanTibble(nc)
head(tbl)

# Tibble based on bbox filtered region

# Kincade fire region
bbox <- c(-124, -120, 36, 39)

filtered_tbl <- goesaodc_createScanTibble(nc, bbox)
head(filtered_tbl)
