Abstract : Apart from blocking most of the X-rays and gamma ray photons from extra-terrestrial sources, the Earth's atmosphere also redirects some of them through Compton scattering. This reflected high energy photons are readily detected by the space born X-ray/gamma ray detectors. The observation of Gamma Ray Burst (GRB) spectra are supposed to be affected by the reflected contribution of the same by Earth's atmosphere. Though there are some rigorous studies of the possible X-ray/gamma ray background contribution from secondary photons (albedo) originated from Cosmic Gamma ray Background (CXB) and Cosmic ray particles, the study of the reflected or albedo contribution in prompt GRB observation from Earth's atmosphere is rare. We aim to study the same through rigorous Monte Carlo simulation program and propose a mechanism for correction of the observed spectrum to effectively remove the albedo contribution. This article describes the Monte Carlo simulation results on the possible albedo contributions on prompt GRB spectral observation through space born high energy detectors.
