Temperature Correction of the Vertical Ozone Distribution Retrieval at the Siberian Lidar Station Using the MetOp and Aura Data

Atmosphere, 2020
The purpose of the work is to study the influence of temperature correction on ozone vertical distribution (OVD) in the upper troposphere–stratosphere in the altitude range~(5–45) km, using differential absorption lidar (DIAL), operating at the sensing ...

Multi-Frequency Differential Absorption LIDAR (DIAL) System for Aerosol and Cloud Retrievals of CO₂/H₂O and CH₄/H₂O

Remote Sensing, 2023
We discuss a remote sensing system that is used to simultaneously detect range-resolved differential absorption LIDAR (light detection and ranging; DIAL) signals and integrated path differential absorption LIDAR signals (IPDA LIDAR) from aerosol targets ...

Measurements of Ozone Vertical Profiles in the Upper Troposphere–Stratosphere over Western Siberia by DIAL, MLS, and IASI

Atmosphere, 2020
The purpose of this work is to measure the ozone vertical distribution (OVD) in the upper troposphere−stratosphere by differential absorption lidar (DIAL) at 299/341 nm and 308/353 nm and to compare and analyze the results against satellite data. А

Differential absorption radar techniques: surface pressure [PDF]

Atmospheric Measurement Techniques, 2014
Two radar pulses sent at different frequencies near the 60 GHz O2 absorption band can be used to determine surface pressure by measuring the differential absorption on and off the band.

Differentiation of Amidase and  -Lactamase by Infrared Absorption [PDF]

Journal of General Microbiology, 1964
SUMMARY: The carbonyl-β-lactam absorption band of penicillins and cephalosporins at 1760 cm.-1 is detectable when the antibiotics are mixed with enzymes or bacterial protein. This band can therefore be used for differentiating the two inactivating enzymes β-lactamase and amidase.

Differential absorption radar techniques: water vapor retrievals [PDF]

Atmospheric Measurement Techniques, 2016
Two radar pulses sent at different frequencies near the 183 GHz water vapor line can be used to determine total column water vapor and water vapor profiles (within clouds or precipitation) exploiting the differential absorption on and off the line.

Performance Evaluation of an A Band Differential Absorption LIDAR Model and Inversion for the Ocean Surface Pressure from Low-Earth Orbit

Atmosphere, 2023
Remote sensing of ocean surface pressure from space is very important, and differential absorption LIDAR and differential absorption radar are only two kinds of remote sensing instruments with this potential.

Boundary-layer water vapor profiling using differential absorption radar [PDF]

Atmospheric Measurement Techniques, 2018
Remote sensing of water vapor in the presence of clouds and precipitation constitutes an important observational gap in the global observing system. We present ground-based measurements using a new radar instrument operating near the 183 GHz ...

Atmospheric Mercury in China Studied with Differential Absorption Lidar [PDF]

EPJ Web of Conferences, 2020
Mercury is a very serious environmental pollutant which is intensely studied by many researchers. China is a main producer and consumer of mercury. We have pursued extensive monitoring of atomic mercury using the differential absorption lidar (DIAL ...
