goes_lonlat

Description

Converts GOES xy radian coordinates to latitude and longitude pairs

Usage

goes_lonlat(x, y, r_eq, r_pol, H, lambda0)

Arguments

x	x value from the netcdf in radians (scale and offset already applied)
y	y value from the netcdf in radians (scale and offset already applied)
r_eq	semi_major_axis
r_pol	semi_minor_axis
H	satellite height from center of earth = perspective_point_height + semi_major_axis
lambda0	longitude_of_projection_origin (converted to radians)

Value

a named list with lon and lat values

Examples

coords <- goes_lonlat(x_rad, y_rad, r_eq, r_pol, H, lambda0)
