The GCOS requirements for atmospheric chemistry observations are implemented within the WMO’s GAW global network of monitoring stations, which has about 20 global stations measuring atmospheric chemistry, surface meteorological data, and with an upper air station nearby, Section The report outlines key elements to consider in designing a program to create climate-quality data from satellites. It examines historical attempts to create climate data records, provides advice. Among other things, this means that no – time series will have any data at all from high above the ground, whereas a – series might have much more data from the upper air than from the surface. As we will see, climate scientists have found numerous ingenious ways to confirm, correct, combine, and reject data.

The need for a reference upper‐air network to better meet the needs of the international climate research community has long been recognized (e.g. Trenberth, ). In response to this need, the inception of the GCOS Reference Upper‐Air Network (GRUAN; GCOS ‐, GCOS ‐) was.

The Global Climate Observing System Reference Upper-Air Network is an international reference observing network of sites measuring essential climate variables above Earth's surface, designed to fill an important gap in the current global observing measurements are providing long-term, high-quality climate data records from the surface, through the troposphere, and into the.

GUAN - Specification of Fields and Variables The observing requirements for the GCOS Upper-Air Network (GUAN) are described below.

See the report "Guide to the GCOS Surface and Upper-Air Networks: GSN and GUAN" for more information on the implementation and operation of the GUAN. Initial selection of a GCOS Surface Network. and GCOS [3] networks, have introduced unwanted inhomogeneity into the time series of surface and upper-air observations.

The concept of essential climate variables in support of climate research, applications, and policy: described is the concept of Essential Climate Variables developed under the Global Climate Observing System for a range of applications, as well as to provide an empirical basis for understanding past, current, and possible future climate variability and change.

The Global Climate Observing System (GCOS) is a co-sponsored programme which regularly assesses the status of global climate observations and produces guidance for its improvement. It is co-sponsored by the World Meteorological Organization (WMO), Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO), United Nations Environment Programme (UN Environment), and.

Among other points, GCOS () concluded that developed countries had improved many of their climate observation capabilities, but there was little progress in ensuring long-term continuity for several important observing systems and in filling gaps in the in situ observing networks, with some evidence of.

This is an interactive blog for the GRUAN community. It allows posting information to everybody interested in the GRUAN and openly discussing relevant issues.

During the first implementation meeting (ICM-1) several participants expressed the need for a communication platform and here it is.

We (the lead centre staff) hope it serves the desired purposes. In the s, gaps in knowledge of climate and declining core observational networks in many countries (Houghton et al.

) led to calls for systematic observation of a limited set of critical provide guidance, the Global Climate Observing System (GCOS) program developed the concept of “essential climate variables” (ECVs), which has since been broadly adopted in science and Cited by: Currently, well over 10 manned and automatic surface weather stations, 1 upper-air stations, 7 ships, moored and 1 drifting buoys, hundreds of weather radars and 3 specially equipped commercial aircraft measure key parameters of.

Task Team on The instigation of a GCOS Surface Reference Network. AOPC (Exeter, UK, March ) agreed on creation of a dedicated task-team to scope a potential GCOS global surface reference network. The potential for such a network has been proposed by.

Moreover, at the Third Conference of the Parties in Kyoto ina resolution was adopted that "(u)rges the Parties to provide the necessary resources to reverse the decline in the existing observational networks and to support the regional and global observational systems being developed under the Global Climate Observing System (GCOS), the.

WMO () reports that the GOS includes some 11 surface observations, upper-air observations, ships ( reporting every day), reports from over cooperating aircraft via the Aircraft Meteorological Data Relay (AMDAR) system, data from a constellation of satellites, and radar data from national and regional networks, plus Cited by: 1.

The Climate Observing System Fund and the GCOS Cooperation Mechanism have supported the improvement of observation deficiencies in some meteorological networks by procuring instruments, from voluntary contributions, for key stations in the Global Surface Network (GSN) and the GCOS Upper-Air Network (GUAN) networks.

Contributing baseline GCOS observations. Global Upper Air Network (GUAN), a subset of around of the global network of radiosonde stations that support weather forecasting.

Chosen to provide the best available coarse resolution global network for detecting changes in temperatures, this network is also useful for upper air winds. For the period of –, intercomparisons are performed with four independent observations platforms: radiosonde (RS92), constellation observing system for meteorology ionosphere and climate (COSMIC), global climate observing system (GCOS) reference upper-air network (GRUAN), and infrared atmospheric sounding interferometer (IASI).

This Meeting also incorporated members of the Advisory Group on GCOS Surface Network (GSN) and GCOS Upper Air Network (GUAN) (AGG), which is an informal group of the GCOS Atmospheric Observational Panel on Climate (AOPC) focusing on performance and technical issues in the networks.

The distinct surface reflectance characteristics of clouds, oceans, deserts and vegetation determine the overall shape of the spectra. The interaction between light and trace gases absorption (e.g., shown in Fig.

The Maïdo high-altitude observatory located in Reunion Island (21° S, ° E) is equipped with the Lidar, an innovative Raman lidar designed to measure the water vapor mixing ratio in the troposphere and the lower stratosphere, to perform long-term survey and processes studies in the vicinity of the tropopause.

The calibration methodology is based on a GNSS (Global Navigation Author: Hélène Vérèmes, Guillaume Payen, Philippe Keckhut, Valentin Duflot, Jean-Luc Baray, Jean-Pierre Camm. Betweenan increasing stability in surface and upper-air observational programmes was achieved and certain cost reductions accomplished.

The upper-air network density remained unchanged in the African, South American and Antarctic Regions. The upper-air network had been increased by 10 stations in the Oceania Region. Study Chapter 5 flashcards from Frankie T.

These data can be collected through various sources such as private initiatives by companies, research programs, and both national and international organisms. They also vary by types, e.g., in situ measurements, satellite, reanalysis and simulated data.
