GENERAL COMMENTS This work by Yin et al. presents an overview of about 5 years of continuous near-surface ozone observations at the Nam Co station which is located in the central Tibetan Plateau. The scope of the paper is rather ambitious: to characterize the typical variability of near-surface O3 at this measurement site, to compare it with other sites in the Tibetan Plateau (and beyond) and t...

I. MOTIVATION Large-scale thawing of arctic permafrost has a poorlyunderstood feedback effect on global climate through the release of CO2 and methane. Active Layer Thickness (ALT) is the maximum annual depth of thaw of surface soils and is designated by the World Meteorological Organization (WMO) as an essential climate variable for monitoring the status of permafrost. Interferometric Syntheti...

Abstract. The precise measurement of the amount fraction atmospheric nitrous oxide (N2O) is required to understand global emission trends. Analysis site-specific stable isotopic composition N2O provides a means differentiate sources. availability accurate reference materials known fractions and critical for achieving these goals. We present development gas underpinning measurements isotope rati...

The history of depletion of stratospheric ozone over Antarctica in the austral spring is well known and well documented from the time of the discovery [Farman et al, 1985]. The rapid increase in this depletion during the 1990s [Solomon, 1999] is now being followed by a leveling off of the annual depletion [Salby et al., 2011]. The cause of this depletion again is well known; excess stratosphere...

This study uses ground and CHIRPS data to rationalize the density of rainfall stations in Jatiroto Sub-watershed, Lumajang Regency. aimed determine suitability satellite measurement data. In addition, it determines based on WMO standards. Also, Kagan-Rodda method station recommendations' results. The used for test value RMSE, NSE, Correlation Coefficient, Relative Error. And standard analyzing ...

This paper starts with summarizing the indications for climate change as they are reviewed in the most recent WMO global climate system reviews. There are indications in the paper for increasing climate variability in certain areas. Some of the principal causes of increasing climate variability and climate change (ICV & CC) are a mixture of external and internal factors to the climate system. O...
