Source: ECMWF SYNOP-SHIP-METAR data coverage The sensors themselves can be either in-situ (hence providing information about their immediate environment) or remote (in which case they are able to measure over distances that extend significantly beyond the location of the instrument itself).ĭata coverage varies, depending on the type of observations to be achieved, and the quantities measured depend on the type of instruments. Observations are described as direct when a physical parameter is measured directly, for example temperature or pressure at a land station. These are measurements (from ground stations, buoys, satellites, etc.) of the occurrence of one or more physical variables (temperature, humidity, wind, etc.) at one or more particular times and places in and on the atmosphere, ocean, etc. The type of climate data you will be using greatly depends on the period of time you are interested in: We have very little actual observations at the scale of climate and usually not covering a large area. When we talk about climate data, the type of data can vary significantly. This is a preliminary list of variables and we will re-discuss it later after learning what is generally on offer. Write in the workshop etherpad the list of variables you think would be useful for your study and at the same time write what you would like to do with climate data (area of application). Source: Which Climate variables do you plan to use? It regularly assesses the status of global climate observations of the atmosphere, land and ocean and produces guidance for its improvement.Īt the moment, there are 54 ECVs divided in 3 categories: GCOS is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization (IOC-UNESCO), the United Nations Environment Programme (UN Environment), and the International Science Council (ISC). The Global Climate Observing System (GCOS) and its GCOS expert panels maintain definitions of Essential Climate Variables (ECVs). That is what we call Essential Climate Variables. However, it is insufficient to fully characterize the climate, and scientists have agreed on a number of variables to systematically observe Earth`s changing climate. Temperature is often the first variable that comes to mind when we talk about climate.
What could happen if CO2 emissions double within the next century? By how much will global temperature at the end of the century be warmer than the beginning of the century? Watch this Video to get an illustration of the difference between climate and weather.Ĭlimate questions are different from weather questions: Source: Animated short on statistics from Norwegian infotainment program Siffer. But there is a big difference between climate and weather: weather varies from hour to hour and from day to day whereas climate is defined as the average of weather over several decades or longer. Quantities that climate scientists are interested in are similar to those used to assess the weather. Take a few minutes to talk in small groups (2 to 3 people) about the definition of climateĪs given by wikipedia. What do you think about wikipedia’s definition of climate? It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.Ĭlimate differs from weather, in that weather only describes the short-term conditions of these variables in a given region. Is it surprising?Ĭlimate is defined as the average state of everyday’s weather condition over a period of 30 years. Let’s have a short discussion alltogether about the words that appear most.
#Climatic data for region x code#
Use the code given by your instructor to enter the corresponding menti room. Go to and give us a list of words that you associate with climate. What is climate?Įverybody has an opinion about climate or climate change, but do we all have the same understanding on what the word climate means? What does the word climate mean to you? Many sections of the present lesson have been taken from the online Copernicus Training material.Ĭopernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European capacity for Earth Observation.
