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,...
...for nowcasting and very short-range forecasts...
...but comes even close to the goal requirements
for high-resolution numerical weather forecasts...
...and even for nowcasting and very short-range forecasts!

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 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)
