Angular diameter Diameter Angular separation Distance Angular size Array processor An article in a Journal. Atmospheric density Atmospheric layer Atmospheric layer boundary Atmospheric radiation Sky radiation Atmospheric tide Aurora Auroral arc Auroral jet Auto-correlation Autocorrelation Axial ratio Azimuth is an angular measure in a spherical coordinate system. The vector from an observer (origin) to a point of interest in the sky is projected perpendicularly onto the equatorial plane; the angle between the projected vector and the reference vector on the reference plane (usually the direction to the sun as it crosses the equatorial plane at vernal equinox) is called the azimuth of the point of interest. Background noise A body of water is any significant accumulation of water, usually covering the Earth. The term body of water most often refers to large accumulations of water, such as oceans, seas, wetlands,and lakes (Source - Wikipedia) Not a physical instance of a Book, but the set of Books of a given title and author. Catalogues in UK The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 2,000 kilometers deep. (Source - Wikipedia) Civil time ClimateZones Computer program Contour map Coordinated Universal Time UTC Cosmic year Count Cross-correlation Cross correlation Crust A collection of facts from which conclusions may be drawn (Source - WordNet #1) The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. (Source - Wikipedia) Data analysis Analysis of data is a process of inspecting, cleaning, transforming, and modeling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making (Source - Wikipedia). Data mining Data mining is a particular data analysis technique that focuses on modeling and knowledge discovery for predictive rather than purely descriptive purposes. Specifically, it is the process of discovering new patterns from large data sets involving methods from statistics and artificial intelligence but also database management. In contrast to for example machine learning, the emphasis lies on the discovery of previously unknown patterns as opposed to generalizing known patterns to new data (Source - Wikipedia). Descriptive statistics Descriptive statistics summarize the population data by describing what was observed in the sample numerically or graphically. Numerical descriptors include mean and standard deviation for continuous data types (like heights or weights), while frequency and percentage are more useful in terms of describing categorical data (Source - Wikipedia.org) Differential equation Distribution function Distribution in space Diurnal phenomena Diurnal variation Dust storm Earth science Engineered construct Engineered geographic features such as highways, bridges, airports, railroads, buildings, dams, and reservoirs, which are part of the anthroposphere because they are man-made, are artificial geographic features. Equatorial zone A documentation or note that corrects an error in an earlier document. Error analysis Error analysis is the study of kind and quantity of error that occurs, particularly in the fields of applied mathematics. In numerical simulation or modeling of real systems, error analysis is concerned with the changes in the output of the model as the parameters to the model vary about a mean. (Source wikipedia.org) fast Fourier transform FFT Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively to less formal judgemental methods. (Source - Wikipedia.org) Fourier transform Frequency analysis Frequency distribution the scientific discipline that deals with the measurement and representation of the Earth, including its gravity field, in a three-dimensional time varying space. terrestrial physics Gregorian calendar Heliocentric Julian Date HJD historical background The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane. This coordinate system divides the sky into the upper hemisphere where objects are visible, and the lower hemisphere where objects cannot be seen since the earth is in the way. The pole of the upper hemisphere is called the zenith. The pole of the lower hemisphere is called the nadir. The horizontal coordinates are: * Altitude (Alt), sometimes referred to as elevation, is the angle between the object and the observer's local horizon. It is expressed as an angle between 0 degrees to 90 degrees. * Azimuth (Az), that is the angle of the object around the horizon, usually measured from the north increasing towards the east. * Zenith distance, the distance from directly overhead (i.e. the zenith) is sometimes used instead of altitude in some calculations using these coordinates. The zenith distance is the complement of altitude (i.e. 90°-altitude). Image processing Image reconstruction Inertial coordinate system Inertial reference frame Inferential statistics Inferential statistics uses patterns in the sample data to draw inferences about the population represented, accounting for randomness. These inferences may take the form of: answering yes/no questions about the data (hypothesis testing), estimating numerical characteristics of the data (estimation), describing associations within the data (correlation) and modeling relationships within the data (for example, using regression analysis). Inference can extend to forecasting, prediction and estimation of unobserved values either in or associated with the population being studied; it can include extrapolation and interpolation of time series or spatial data, and can also include data mining (Source Wikipedia). Inner core A concept with an inventor or a group of inventors, possibly the human race, as in fire. A product of the imagination Julian calendar Julian Date A landform comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such, is typically an element of topography. Landforms are categorised by features such as elevation, slope, orientation, stratification, rock exposure, and soil type. They include berms, mounds, hills, cliffs, valleys, rivers and numerous other elements. Oceans and continents are the highest-order landforms. (Source - Wikipedia.org) Light pollution Line identification Line of sight Statistical relation The rigid outermost shell of a rocky planet. On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. Location is meant here to be more general than position. It includes indirect references to position, like an address or PO Box, or location in memory. Position is a direct spation location like (x,y,z) or l,b. Location behind Location between Location in front Magnetic anomaly Magnetic disturbance Magnetic storm Magnetosphere Magnetospheric substorm Major axis Mantle Mathematical analysis Mathematical model Mean solar time A Property that has Units, Value, and Error, ie a Quantity Mechanical property Location in Memory. Usually a hex number. A great circle of the celestial sphere passing through its poles and the zenith of a given place (Source - http://www.merriam-webster.com) A method is a series of steps or acts, for performing a function or accomplishing a result Mineral deposit Minor axis The making of a limited change in something (Source - www.merriam-webster.com#3a).

Semimajor axis semi-major axis Semiminor axis semi-minor axis A settlement is a permanent or temporary community in which people live. A settlement can range in size from a small number of dwellings grouped together to the largest of cities with surrounding urbanized areas. Sidereal time ST Signal detection Signal processing Signal processing is an area of electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time, to perform useful operations on those signals. Signals of interest can include sound, images, time-varying measurement values and sensor data.(Source - wikipedia.org). Signal-to-noise ratio (SNR) signal to noise ratio Solar transition region The solar transition region is a region of the Sun's atmosphere, between the chromosphere and corona. It is visible from space using telescopes that can sense ultraviolet. Southern hemisphere Space exploration Space geodesy Space law Space pollution Space probe Statistics Statistics is the study of the collection, organization, and interpretation of data. It deals with all aspects of this, including the planning of data collection in terms of the design of surveys and experiments (Source - Wikipedia). SubpolarZone SubtropicalZone TemperateZone Terrestrial radiation Thermal history Time standard Topography (from Greek τόπος topos, "place", and γράφω graphō, "write") is the study of Earth's surface shape and features or those of planets, moons, and asteroids. It is also the description of such surface shapes and features In a broader sense, topography is concerned with local detail in general, including not only relief but also vegetative and human-made features, and even local history and culture. This meaning is less common in America, where topographic maps with elevation contours have made "topography" synonymous with relief. The older sense of topography as the study of place still has currency in Europe and that is what is meant here (Source - Wikipedia.org) Tropical year TropicalZone Turbidity is the cloudiness or haziness of a fluid caused by individual particles (suspended solids) that are generally invisible to the naked eye, similar to smoke in air.
