Data

The Pandora spectrometer system is an instrument developed to measure vertical column densities of trace gases in the atmosphere using sun/lunar and sky radiation in the UV-visible part of the spectrum. Among currently experimental data products, such as SO₂ and HCHO, validated and near-real-time O₃ and NO₂ total vertical column density (VCD) data products are included.


Extensive scientific literature has been reported regarding the validation of Pandora direct-sun NO₂ VCD products through satellite validations, field campaigns and ground-based comparisons.


Since their introduction in 2006, many improvements have been applied to Pandora instruments, amongst them, improvements in software and hardware (blick software suite, new tracker, head sensor, fiber guide holder, and support frame), standard procedures (calibration, operations and maintenance), assurance and quality control standards, and supporting long-term reference instruments, for example, at NASA Goddard Space Flight Center.
