"MCFE - P" for gas pre filtration with efficiency E > 99% for particles with d > 1.5 mm under P  15 mm H₂O;

"MCFE - H" for gas cleaning with high efficiency E > 99.9999% for particles with d > 0.01 mm under P  100-140 mm H₂O;

"MCFE - U" for gas cleaning with ultra efficiency E > 99.9999995% for particles with d > 0.01 mm under P  170 mm H₂O.

Here P is a differential resistance of material at the air filtration rate U = 1 cm/sec at 20 °C. E is the efficiency at U = 5 cm/sec.

Present Status of Research

Brief Description of Research

Approximately ten years ago the ICRCCM international working group (on the InterComparison of Radiation Codes used in Climate Models) selected more than a hundred of test cases for testing of radiation codes being used in climate models and suggested to create a databank of so-called "benchmark calculations" for this testing. Owing to the ISTC support (project 23) the exact line-by-line codes effective enough to solve the problem of the benchmark calculations have been developed and the above databank has been created.

These codes, combined into a complete integrated system, provide a powerful tool for 'ab initio' modeling of radiation properties of the Earth atmosphere and the algorithms being used in these codes may be easily incorporated into a variety of applied information systems for satellite experiments and other applications.
