goesaodc_calcTrendScanRaster: Calculate the trend raster of a series of GOES scan rasters

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

Description

Creates a SpatialPointsDataFrame of AOD trend values from a GOES scan rasterBrick. A trend value for a cell is calculated by taking the difference between it's average value in the first half of the scan series and it's average value in the second half.

Usage

goesaodc_calcTrendScanRaster(rasterBrick = NULL, na.rm = FALSE)

Arguments

rasterBrick	RasterBrick of GOES scan RasterLayerss.
na.rm	Logical flag whether to remove NA values before calculating the trend. Defaults to FALSE.

Value

RasterLayer that is the trend of all the RasterLayers in a RasterBrick.

Examples

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

bboxOregon <- c(-125, -116, 42, 47)

scanFiles <- goesaodc_listScanFiles(
  satID = "G17",
  datetime = "2020-09-08 12:00",
  endtime = "2020-09-08 13:00",
  timezone = "America/Los_Angeles"
)

scanRasterBrick <- goesaodc_createScanRaster(
  filename = scanFiles,
  bbox = bboxOregon,
  cellSize = 0.05
)

goesaodc_calcTrendScanRaster(
  rasterBrick = scanRasterBrick,
  na.rm = TRUE
)
