Introduction to Climate Models
This module explains how climate models work. Because the modeling of both weather and climate share many similarities, the content throughout this module draws frequent comparisons and highlights the differences. We explain not only how, but why climate models differ from weather models. To do so, we explore the difference between weather and climate, then show how models are built to simulate climate and generate the statistics that describe it. We conclude with a discussion of models are tuned and tested.

The Scientific Fundamentals of Climate Change
The climate system is a complex, interactive system consisting of the atmosphere, land surface, snow and ice, oceans and other bodies of water, and living elements. The climate system evolves in time under the influence of its own internal dynamics and due to changes in external factors. But, do you know what the meteorological consequences of climate variability and change are? What is the human contribution to climate variability?

Meteorological Instrument Performance Characteristics
NCAR's Earth Observing Laboratory ; The COMET Program ; Millersville University - The University Corporation for Atmospheric Research, 2017This advanced lesson explores the performance characteristics of instrumentation used for meteorological measurements. Static performance characteristics are examined in the context of calibration, which offers a means to determine an instrument's response. Dynamic performance characteristics, including first and second order inputs, are discussed using three classic examples: step or impulse, ramp or time varying, and oscillatory inputs. The lesson provides information about the effects of representativeness and regional homogeneity on measurements, and also describes processes for obtaining ...

Directives de l’OMM pour le calcul des normales climatiques
Le présent document traite avant tout des observations réalisées dans les stations météorologiques en surface. Toutefois, bon nombre des principes exposés ici s’appliquent également à d’autres formes de relevés, comme les observations aérologiques et les jeux de données obtenus à partir de plateformes mobiles ou de télédétection (satellites, radars ou bouées dérivantes par exemple). Comme les jeux de données obtenus par télédétection remontent le plus souvent jusqu'aux années 70, il est recommandé de leur appliquer, dans la mesure du possible, la période climatologique standard actuelle (1981- ...PermalinkPermalinkPermalinkPermalink![]()

Challenges in the Transition from Conventional to Automatic Meteorological Observing Networks for Long-term Climate Records
Guidelines for managing changes in climate observation programmes, with a set of recommended practices by which such changes can be managed, have already been published (WMO, 2007). This guidance note will focus on those AWSs likely to form part of long-term climate records. These will normally be owned by NMHSs or associated agencies, or sometimes by third parties (such as aviation, agriculture or road transport agencies) under standards endorsed by the NMHSs. Experience shows that private AWSs can be useful for some climate purposes (such as providing information on individual local-scale ex ...Permalink![]()

Вместе с тем многие принципы также будут действительны для других форм наблюдений, включая аэрологические наблюдения и комплекты данных с мобильных платформ и платформ дистанционного зондирования (например, спутников, радиолокаторов или дрейфующих буев). В частности, в связи с тем, что многие основные комплекты данных дистанционного зондирования берут свое начало в 1970 х гг., рекомендуется по возможности использовать в отношении этих комплектов данных текущий период климатологическ ...Permalink![]()

WMO Guidelines on the Calculation of Climate Normals
The focus of this document is on observations at surface meteorological observing stations. However, many of the principles will also be valid for other forms of observations, including upper-air observations and datasets based on mobile or remotely sensed platforms (for example, satellites, radar or drifting buoys). In particular, as many key remotely sensed datasets begin in the 1970s, it is recommended that, where feasible, the current climatological standard normal period (1981–2010 at the time of writing) be used for these datasets to allow comparison among different data forms on a consi ...PermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalink![]()
