Development and Evaluation of a New Method for AMSU-A Cloud Detection over Land

open access: yesRemote Sensing, 2021
Satellite data are the main source of information for operational data assimilation systems, and Advanced Microwave Sounding Unit-A (AMSU-A) data are one of the types of satellite data that contribute most to the reduction of numerical forecast errors ...

TITAN'S SURFACE BRIGHTNESS TEMPERATURES

open access: yesThe Astrophysical Journal, 2009
Radiance from the surface of Titan can be detected from space through a spectral window of low opacity in the thermal infrared at 19 μm (530 cm–1). By combining Composite Infrared Spectrometer observations from Cassini's first four years, we have mapped the latitude distribution of zonally averaged surface brightness temperatures.

Limiting Brightness Temperature for Synchrotron Sources [PDF]

open access: yesInternational Astronomical Union Colloquium, 1998
AbstractThe maximum brightness temperature limit for synchrotron sources derived from inverse Compton catastrophe is usually taken to be 1012 K. Readhead has argued in 1994 that the equipartition brightness temperature may be a better estimate for Tb,lim. It provides a value of 5 × 1010 K.

Temperature and Brightness Variations on Betelgeuse [PDF]

open access: yesSymposium - International Astronomical Union, 1986
Changes in Ti0 band strengths correlate well with the brightness changes of α Orionis, thus supporting the hypothesis of Schwarzschild that the irregular luminosity variations of red giants are due to temperature changes in a few extremely large convective elements on their surface.
