All sky imaging visible infrared analyzer

The ASIVA all sky imaging visible infrared analyzer is a monitoring device that provides multi-purpose visible light, sky imaging, and infrared analysis. It can detect and apply clouds in the sky, astronomical sky imaging analysis systems, solar energy prediction, and various meteorological monitoring and applications.

Product features:

6: Determination of water vapor and ozone

7: Sky/Cloud Temperature (Brightness and Color) Measurement

8: Radiation map and analysis of the entire sky (180 degree field of view)

9: Further functional research, design, and implementation are currently underway

10: Predictive Cloud Coverage Report

Function:

Providing a radiometric calibration image infrared (IR) atmospheric window, which can directly detect cloud emissions from a thermal infrared imager at 8-13 micrometers (μ m), has significant advantages over relying on scattered light or blurry starlight, unaffected by the moon (or sun), thus providing consistent and reliable information under various conditions.

Custom data products can be developed by customers or Solmirus to meet specific application requirements.

Scalable satellite camera function

The following figure shows the simulation of radiation using MODTRAN on standard mid latitude summer atmosphere pointing to different zenith water vapor (PWV) under clear sky.The display conditions (1 millimeter and 5 millimeter PWV) are usually encountered at observatories.

The absorption wavelength of thermal radiation is less than 8 μ m, mainly composed of water vapor. The absorption wavelength of carbon dioxide and ozone with wavelengths greater than 13 μ m is close to 9.5 μ M Water vapor is absorbed to cover the entire spectral range between the uncommon 10.2-12.2 μ M. For this purpose, Solmirus provides a custom 10.2-12.2 μ M filter to optimize the contrast of clear sky/clouds. The spectral response of this filter (in red) is shown in the following figure, providing two filters commonly used in tools. Provide a spectral filter of 10.2-12.2 μ M to determine sky spectral radiation (and brightness temperature).

A typical sky radiation filter with an absolute radiation accuracy of 10.2-12.2 μ M calibrated in the laboratory is ± 0.2W/㎡ - μ m-Sr, which is equivalent to an accuracy of ± 1.4 ℃ at a temperature of 300 ℃. This high pixel detector can uniquely detect thin clouds and cirrus clouds. The following image shows the infrared and visibility, and the sky is completely covered by thin cirrus clouds, making it less likely to appear in visible light images.

The analysis program of the ASIVA all sky imaging visible infrared analyzer is currently in progress to extract data on water vapor, ozone, cloud temperature, cloud height, and other attributes. The following figure provides the theoretical sensitivity of precipitation potential (PWV) in three other commonly used filters.
