In recent years, the air pollution is becoming more and more serious, which not only causes the decrease of the visibility, but also affects the human health. As the most important pollutant particula...
INTER-ANNUAL HEIGHT VARIATIONS OBSERVED BY GPS MEASUREMENTS IN TURKEY
Inter-annual signal, Height, GPS, Climate change
2018/5/8
Turkey is located in Africa-Eurasia-Saudi Arabian plate converged areas with surrounding by the Black Sea and the Mediterranean Sea. Apart from its tectonic conditions, the climate is complexly varyin...
Maximum-likelihood reconstruction of photon returns from simultaneous analog and photon-counting lidar measurements
Maximum-likelihood reconstruction photon return simultaneous analog photon-counting lidar measurement
2011/8/2
Abstract: We present a novel method for combining the analog and photon-counting measurements of lidar transient recorders into reconstructed photon returns. The method takes into account the statisti...
Measurements of Gaseous NH3 and Particulate NH4 + in the Atmosphere by Fluorescent Detection after Continuous Air–water Droplet Sampling
Ammonia Gas-particle partitioning Microflow analysis Short-term variation
2016/3/28
Phase partitioning of NHx (gaseous NH3 and particulate NH4
+) in the atmosphere is crucial for the lifetime of NHx
during atmospheric transport. Reliable data for gaseous NH3 and NH4
+ in aerosols ...
Continuous isotopic composition measurements of tropospheric CO2 at Jungfraujoch (3580 m a.s.l.), Switzerland: real-time observation of regional pollution events

2011/2/25
Polar Mesosphere Summer Echoes (PMSE) and Noctilucent Clouds (NLC) have been routinely measured at the ALOMAR research facility in Northern Norway (69° N, 16° E) by lidar and radar, respectively. 2900...
Simultaneous HONO measurements in and above a forest canopy: influence of turbulent exchange on mixing ratio differences
HONO measurements a forest canopy turbulent exchange ratio differences
2011/2/24
We have combined chemical and micrometeorological measurements to investigate the formation and distribution of HONO throughout a forest canopy. HONO was measured simultaneously at two heights, close ...

tropical ocean clouds moist water vapor isotope measurements
2011/2/24
We examine the co-variations of tropospheric water vapor, its isotopic composition and cloud types and relate these distributions to tropospheric mixing and distillation models using satellite observa...
Assessment of fossil fuel carbon dioxide and other anthropogenic trace gas emissions from airborne measurements over Sacramento, California in spring 2009
fossil fuel carbon dioxide anthropogenic trace gas airborne measurements Sacramento California
2011/2/24
Direct quantification of fossil fuel CO2 (CO2ff) in atmospheric samples can be used to examine several carbon cycle and air quality questions. We collected in situ CO2, CO, and CH4 measurements and fl...
