Profiler Network

The New York State Mesonet operates a network of 17 profiler sites. Each profiler site is comprised of a scanning Doppler LiDAR and a microwave radiometer. All data are collected, quality-controlled, and archived in real-time every 10 minutes. Data displayed here are provisional and may not always be available. Product development is ongoing, and this page will be updated as products are refined and as more profiler sites come online. For the time-series plots below, the most recent data available is on the right side of each plot.

For technical information about our profiler network, please review the readme file. You may request profiler data by visiting our data request page and choosing the profiler network from the dropdown list.

Each profiler site is equipped with a Leosphere WindCube WLS-100 series Doppler LiDAR (Light Detection and Ranging). The LiDAR uses a vertically-pointing eye-safe laser to estimate wind velocities in the vertical. The LiDAR measures the speed and direction of aerosols moving towards and away from the beam, and the reflected energy is analyzed to determine 3-D wind speed and direction. During times of low aerosol concentration, data availability may be limited. The Carrier to Noise Ratio (CNR) plot is a measure of reflected energy as detected by the sensor. Data availability is poor when the CNR is below -25 dB.

Microwave Radiometer

Each profiler site is equipped with a Radiometrics MP-3000 series microwave radiometer. This is a passive instrument that measures the downwelling microwave radiation to estimate vertical profiles of temperature, humidity, and liquid up to 10 km above ground level. The plot shows the last 24 hours of the four output variables: temperature, liquid, vapor density, and relative humidity. A thin red or green line above each plot indicates the self-assigned quality assurance flag for each time step and each variable. Manual calibrations using liquid nitrogen are performed regularly at each site approximately every 6 months.
