Meteorologische Zeitschrift 15 (3): 259–263.) (Markus Kottek, Jürgen Grieser, Christoph Beck, Bruno Rudolf and Franz Rubel. For this information, the gazetteer "Geonames" is used as well. Alternatively, you can set a name manually. A gazetteer is used to generate the name ( ). The Walter-Lieth Chart contains a number of components, which will be explained in the following: In the default setting, the Walter-Lieth Chart is displayed after generation.Ģ.1 Walter-Lieth Climate Chart 2.1.1 Structure of the Walter-Lieth Chart In the upper left corner (1) you can switch between the three different visualizations. After you have created aĬlimate chart with the button "Create Chart" you will get the following view: 2 VisualizationsĬurrently, three different types of climate charts can be generated. The "Reset"īutton is used to set the most recent time period with a length of 30 years (4). Only the data of the selected period is processed and displayed in the climate chart. The upper and lower limits (3) of the light grey bar. The selected time period can be adjusted individually by moving The maximumĪvailable time period for the selected data set (2) is shown in white. Maximum time period in which data (independent of the selected dataset) is available. The web applicationĬ offers the possibility to adapt this period according to your own requirements.įor this purpose, a slider for adjusting the period (1) is available. 1.3.2 Time PeriodĬlimate diagrams are often generated for a period of at least 30 years. You can find more information about the datasets in the menu "Datasets & Software". The selection menu is located beneath the map.Īfter you have chosen the preferred data set, you can select a location in the map. One of these data sets before clicking on a location in the map. In addition, three different raster data sets can be used to generate climate diagrams. This data set is automatically selected whenever a user clicks on a station (cf. The weather stations’ data set is part of the Global Historical Climatology Network (GHCN). Overall, four data sets are available for the generation of climate charts. This popup alsoĬontains information about the name of the place you have selected (3) as well as information about the climateĬlasses according to Köppen-Geiger, the altitude and the selected time period (4). You can also see that you have selected a station by the note "Climate Station" in the popup (2). If you click on one of the brown marked dots on the map, a weather station is selected. With theīutton "Create Charts" a diagram is created below the map (5). This popup also contains information about the name of the place you have selected (3) as well as informationĪbout the climate classes according to Köppen-Geiger, the altitude and the selected time period (4). Another indicator that youĪre seeing raster instead of station data is the note "Climate Cell" at the top of the information popup (2). Within this grid cell the resulting climate diagrams are identical. Once you selected a raster data set and clicked on a location, the corresponding raster cell is shown on the In this case a raster cell at this position is selected. In addition, it is also possible to select a position on the map by entering coordinates into the filter menu. There are two types of data sets available - raster data (see 1.2.1) and station data (see 1.2.2). You can control the labels (degrees or radians) to include and other settings like paper orientation, paper size, margins etc.īrowse our section of pre-made templates for ready to download commonly used papers.The selection of a location is quite easy and is done by clicking on a position in the map. You can change the thickness of the circles and spokes as well as the number of circles and spokes. Now you can create your own polar graph paper with this Polar Graph Paper Maker Tool. Polar graph papers are popular for plotting polar coordinates and generally used in mathematical, engineering and scientific projects. Simply put, concentric circles, equally spaced and divided into arcs using spokes, starting from the center of the circle to the circumference of the outermost circle. It consist of a radial distance from the origin and a rotation of an angle in degrees or radians counter-clockwise from the polar axis. Polar graph paper also known as polar coordinate paper, is a graph paper with concentric circles.
