For example, aspects of the landscape such as soil composition, temperature, and precipitation all factor in to an accurate idea of habitable territory a plant species might occupy; information on one of those factors can help form an environmental gradient by which a proximate species distribution may be generated.

The 18 O/ 16 O ratio in calcite and ice core samples used to deduce ocean temperature in the distant past is an example of a temperature proxy method. The remnants of plants, and specifically pollen, are also used to study climatic change. Plant distributions vary under different climate conditions.
In a recent study, [13] researchers from 63 countries combined 30-minutes rainfall data in order to estimate the global rainfall erosivity (an index combining the amount, frequency and intensity of rainfall). The arid and cold climate zones have very low number of erosive events.
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are A (tropical), B (arid), C (temperate), D (continental), and E (polar).
The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents. [3] Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme is the Köppen climate classification.
The numerical index is based on an overall interpretation of the available documentary evidence indicating the temperature or precipitation conditions of a particular month or season. The so-called Pfister index is the most widely used temperature and precipitation index. [4]
A visualisation of the South Asian Monsoon based on the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) 30+ year quasi-global rainfall dataset, analysed and visualised using Google Earth Engine. Annual average monsoon precipitation in India over 110 years. The long-term average has been 899 millimeters of precipitation. [1]
These factors can each influence the safety of marine transit. Consequently, a variety of codes have been established to efficiently transmit detailed marine weather forecasts to vessel pilots via radio, for example the MAFOR (marine forecast). [104] Typical weather forecasts can be received at sea through the use of RTTY, Navtex and Radiofax.
