DIAL Atmospheric Profiler DA10

Vaisala DIAL Atmospheric Profiler DA10 is a highperformance differential absorption lidar (DIAL) instrument for enhanced severe weather forecasting and climate modeling with advanced, real-time water vapor profiles. DA10 offers continuous and unattended real-time water vapor profiling for operational

observation networks.

Continuous data for forecasting and modeling

DA10 is an ideal instrument for weather nowcasting, forecasting, climate modeling, and atmospheric research.

Because of continuous water vapor mixing ratio profiles, it is particularly well suited for severe weather forecasting

and nowcasting. DA10 measures the water vapor content in the atmosphere from low altitudes up to the top of the boundary layer or cloud base layer – whichever is lower. The advanced real-time water vapor profiles can be used as input to severe weather nowcasting and, for example, for the possible detection of atmospheric rivers. The measurement data is continuous, making DA10 an ideal solution for operational observation networks.

Advanced DIAL technology and optics

DA10 is essentially a ceilometer and a water vapor profiler combined. It provides cloud height information and real-time high-quality water vapor profiling data, as well as atmospheric profiles such as the attenuated backscatter profile. The instrument uses 2 wavelengths of a near-infrared laser source and has 2 measurement units, with telescopes for far-range and near-range measurements. This together with the single-lens technology enables optimum performance over the full measurement range.

Portable and versatile netCDF data

The measurement data is available in the universal and accessible netCDF format. This allows for integration to various types of systems, but also sharing of files across organizations. The netCDF data includes both measurement data and monitoring data. This makes the data easily available for numerical weather prediction (NWP) models.

Uninterrupted autonomous operation

Vaisala instruments are made to perform in extreme weather conditions, and DA10 is no exception. The optics, electronics, and powering components are housed in a weather-proof cabinet, and have been thoroughly tested to ensure operation in demanding conditions.

DA10 is an eye-safe instrument with modern communication and network capabilities. The integrated security software keeps your instrument and data safe.

The instrument operates unattended, with extensive self-diagnostics and embedded fault analysis minimizing downtime. The monitoring data is available to network operators remotely. The need for site visits is minimal because the instrument does not need field calibration or regular maintenance. These contribute to the overall low cost of ownership.
