Short summary
We present an improved instrument for the simultaneous detection of atmospheric nitrous acid (HONO) and nitrogen dioxide (NO2). The robustness of the system is verified by simulating the influence of the relative change in light intensity on the measurement results. The instrument's capability to make fast high-sensitivity measurements of HONO and NO2 is of great significance for understanding the source of HONO and studying its role in atmospheric chemistry.
