The Purple Pulse Lidar System
is the first remote sensing system
exceeding the WMO breaktrough requirements
for water-vapor and temperature measurements
throughout the lower troposphere...

...for high-resolution numerical weather forecasts,...

   see www.wmo-sat.info/oscar/requirements/view/341 and https://www.wmo-sat.info/oscar/requirements/view/379

       

...for nowcasting and very short-range forecasts...

   see www.wmo-sat.info/oscar/requirements/view/427 and https://www.wmo-sat.info/oscar/requirements/view/704

       

...but comes even close to the goal requirements
for high-resolution numerical weather forecasts...

   see www.wmo-sat.info/oscar/requirements/view/341 and https://www.wmo-sat.info/oscar/requirements/view/379

       

...and even for nowcasting and very short-range forecasts!

   see www.wmo-sat.info/oscar/requirements/view/427 and https://www.wmo-sat.info/oscar/requirements/view/704

       

Unequaled resolution and accuracy of water-vapor and temperature profiles!

High resolutions of up to 1 s and 7.5 m

Temperature (T):
    Systematic error < 0.5 K
Water-vapor mixing ratio (WVMR):
    Systematic error < 5 %

T and WVMR profiles exceed WMO goal and breakthrough requirements*, respectively, for nowcasting/VSRF in the lower troposphere
*see OSCAR and plots on the left

Only system capable of resolving temperature inversions, lids, and true atmospheric boundary layer depth

Diode-laser pumped eye-safe transmitter with extraordinary lifetime and low maintenaince

Continuous vertical profiling and 3D scanning systems


Properties of daytime temperature measurements:

    •   Systematic error < 0.5 K
    •   Statistical error < 0.5 K up to 3.5 km
        at 5 min, 100 m resolutions
        exceeding all WMO goal requirements
    •   50 m – 300 m vertical resolution
    •   10 s – 10 min temporal resolution

Properties of daytime water-vapor mixing-ratio measurements:

    •   Systematic error < 5 %
    •   Statistical error < 5 % up to 3.0 km
        at 10 min, 300 m resolutions
        exceeding all WMO breakthrough requirements
    •   50 m – 300 m vertical resolution
    •   10 s – 10 min temporal resolution
    •   Fulfills also all WMO goal requirements up to 1.7 km
       (< 2 % at 5 min, 100 m resolutions)
