ASIVA — All Sky Infrared Visible Analyzer

The Solmirus All Sky Infrared Visible Analyzer (ASIVA) is a multi-purpose visible and infrared sky imaging and analysis instrument designed to operate autonomously or as a component in an instrument cluster. A ground-based cloud detection and sky analysis system with applications ranging from astronomy to solar forecasting to a wide variety of meteorological applications.

The ASIVA is an innovative instrument that can be customized to your research or application needs — encompassing several configuration options, imaging parameters, and on-board data product calculation capabilities, designed to fit seamlessly into your application or data collection workflow.

Data Products & Measurements

Cloud Detection & Cover

Cloud/no-cloud reporting, cloud cover percentage, and cloud height determination in user-defined fields of view.

Sky & Cloud Temperature

Brightness and color temperature measurements per pixel — plus sky opacity/transmission determination across the full hemisphere.

Atmospheric Composition

Water vapor and ozone determination, plus photometric quality assessment for observatory and research applications.

Radiometric Mapping

Full 180° all-sky radiometric maps, visible/IR image correlation and integration, and predictive cloud cover reporting.

ASIVA all-sky radiometric imagery — cloud cover assessment and sky condition analysis

Infrared Subsystem

The ASIVA's primary functionality is radiometrically calibrated imagery in the mid-infrared (mid-IR) atmospheric window spanning 8–13 µm. A thermal IR imager has the distinct advantage of directly detecting emission from clouds rather than relying on scattered light or obscured starlight — unaffected by the Moon or Sun — providing consistent, reliable sky condition data under a wide variety of conditions.

Visible Subsystem

The ASIVA also includes a highly capable visible subsystem consisting of a 5-megapixel monochrome CMOS detector coupled with a 180° high-quality fisheye lens designed for water tightness. A protective glass dome is available for full weatherproofing. An optional 8-position filter wheel for 1-inch filters is available.
