In AlexCast/apsfs: Monte Carlo code for simulation of atmospheric Point Spread Functions and spatially-resolved Spherical Albedo Functions

Grid simulations

Description

Contains the atmospheric point spread functions (APSFs) for nadir, 30 and 60 degrees vieweing sensors, simulated for the continental (con) standard aerosol model of the 6SV radiative transfer code. Simulations were carried out without Rayleigh contribution, and with an aerosol scale height of 2 km. Sensor was positioned at TOA, with an infinitesimal field of view. The vertical optical thickness for all aerosol simulations was 0.5. It is noted, however, that dependence os the normalized APSF on optical thickness is small. By construction, aerosol APSF have no pressure dependence. All simulations are for a sensor altitude of 800 km, but altitude dependence is only significant at altitudes lower than 10 km (aircraft, drones).

Usage

gsim

Format

A list with the following components:

• conv00: APSF simulation for the continental aerosol type at 0 degree view angle;

• conv30: APSF simulation for the continental aerosol type at 30 degree view angle;

• conv60: APSF simulation for the continental aerosol type at 60 degree view angle.

Details

Simulations run with the grid accumulator geometry.
