What is space weather? Space weather refers to the condition of space environment around the Earth as a result of various driving forces from the Sun and from terrestrial processes. As modern technology relies more heavily on infrastructures that we put into orbit in space, many of our everyday high-tech services have become increasingly vulnerable to adverse space weather. An important component of space weather is the condition of the Earth’s ionosphere, a partially ionized portion of our upper atmosphere between 100-1000 km altitude. Any sharp gradients, periodic wave undulations, or turbulent eddies in the ionosphere may influence radio wave propagation and could affect many related technologies — including high-frequency (HF) radio communications, long-range surveillance radars, and GPS-based navigation. A wide range of ionospheric plasma phenomena can be examined using combinations of satellite-borne and ground-based measurements, including the rapidly growing network of GPS receiver stations that are distributed worldwide. In the long-run, such efforts would help us achieve better situational awareness of space weather condition for the wider population in numerous areas of applications.

What are equatorial plasma bubbles (EPBs)? Equatorial plasma bubbles (EPBs) are large-scale turbulent structures that may appear in the ionospheric layer over low-latitude regions during nighttime hours, due to a process known as the Rayleigh-Taylor instability. This instability amplifies small perturbations at the bottomside F-region ionosphere into towering plumes that are filled with a full spectrum of plasma density irregularities and eddies. When fully formed, EPBs appear as large-scale plumes that are geometrically shaped like a series of rugged arches that align themselves north-south and extend approximately ±20 degree latitude from the geomagnetic equator line — following the Earth’s magnetic field lines. The probability of EPB occurrence during post-sunset hours follows a regular long-term climatology that varies spatially around the globe as a function of longitudes, and seasonally as a function of day-of-year. On a day-to-day basis, the probability of EPB occurrence is also affected by the geomagnetic condition, specifically as a function of the Kp index. It is important to monitor and, if possible, forecast the occurrence of EPBs since they can degrade the quality of GPS signals and disrupt radio communications. The following animation below illustrates the typical geometry of EPBs and their evolution (from a mathematical simulation) in a 3-dimensional perspective:
What is low-latitude ionospheric scintillation (due to EPBs)? Ionospheric scintillation is the fluctuation of radio-frequency signal amplitude and/or phase, as a result of the signal passing through turbulent structures in the ionosphere. These turbulent ionospheric structures essentially act as a (severely crooked) diffraction grating that deforms the signal wavefront and scatters the wave energy non-uniformly. In low-latitude regions, ionospheric scintillation typically occurs during the nighttime hours, as the scintillation is caused by plasma density irregularities that exist inside the plumes of EPBs. Ionospheric scintillations are considered an adverse ionospheric phenomenon since they may be detrimental to the quality of signals from navigation and/or communication satellites. Severe ionospheric scintillation conditions can prevent a GPS receiver from locking on to the satellite signal and make it impossible to calculate position accurately. The following animated diagram below illustrates an example situation where we have ionospheric scintillation in GPS signals due to EPBs, contrasting it to the case where GPS signals have a clear line-of-sight:
What are traveling ionospheric disturbances (TIDs)? Traveling ionospheric disturbances (TIDs) are wavelike oscillatory fluctuations in the ionospheric plasma density, which look just like ripples of water waves in a pond or a lake. In some circumstances, TIDs may be caused by acoustic-gravity waves (AGWs) propagating upward from the lower atmosphere into the ionosphere. The underlying AGWs themselves may come from either natural sources or man-made sources. In other set of circumstances, TIDs may also be caused by certain ionospheric plasma instability process that is instrinsic to the mid-latitude region, even when strong AGWs were absent. The occurrence of TIDs may affect the propagation of high-frequency (HF) radio waves over long distances due to the sinusoidal undulations they cause at the bottomside ionosphere. In practice, TIDs may be observed using a variety of ionospheric diagnostic instruments such as ionosondes, incoherent scatter radars, and GNSS total electron content (TEC) measurements. The animation below shows an example of TIDs seen in (high-pass filtered) TEC observation data using dense network of ground-based GNSS receiver network in the United States:
What is an ionosonde? An ionosonde is a high-frequency (HF) radio remote sensing instrument that is often used to measure the altitude profile of ionospheric plasma density. An ionosonde works as a frequency-swept radar that operates using radio wave frequencies of roughly a few MHz, with a rather wide antenna beamwidth (a half-width of ~45 deg). An ionosonde is usually used as a reflectometry or time-of-flight diagnostic instrument, where different sounding frequencies will penetrate the ionospheric layer up to different reflection heights before being reflected back. The time delay Δt at various sounding frequencies can be multiplied by c/2 (where c is the speed of light in free space) to obtain the virtual reflection height. A plot of virtual height c Δt /2 as a function of sounding frequency f is commonly referred to as an ionogram, which provides useful partial information on the shape of the ionospheric layer. Although an ionosonde is most commonly used as a reflectometry ionospheric diagnostic instrument, with its rather wide beam it can also produce some sort of radio-image of the ionospheric layer above the ionosonde station. This radio image is often called a skymap. Return echoes received by an ionosonde may come from total reflection and/or scattering. If there is a significant ionospheric plasma drift, then there will be significant Doppler shift registered in the ionogram or in the skymap as well. In the case of a uniform horizontal plasma drift in the ionosphere, roughly half of the sky will have blueshifted echoes and another half will have redshifted echoes. In the presence of some traveling ionospheric disturbances (TIDs), there might be a distinct pattern of banded cluster with opposite-polarity Doppler shifts. In order to truly master the art of ionogram interpretation, one is encouraged to study the 1972 URSI Handbook of Ionogram Interpretation and Reduction (a.k.a. the UAG-23A technical document) and practice extensively with many different cases of real-world ionograms. Specifically about ionograms in low-latitude regions, the NIST/NBS Technical Note No.145 is also valuable.
What is the total electron content (TEC)? The total electron content (TEC) is the total aggregate number of plasma electrons contained within a slender imaginary cylindrical tube crossing the ionospheric layer. One end of this imaginary cylindrical tube is typically at a ground receiver station, while the other end is at a GPS satellite in orbit — because the TEC is most commonly deduced based on the difference in wave propagation effects between the L1 and L2 signals transmitted by the GPS satellites. More specifically, with the GPS technique, the TEC along a line-of-sight (LOS) is deduced based on the amount of phase advance(s) and group delay(s) experienced by the GPS L1 and L2 signals as these electromagnetic signals propagate through the ionosphere along the LOS. The TEC itself is measured in a physical unit of electrons per cross-sectional area of the imaginary cylindrical tube (1 TEC Unit = 1 TECU = 1016 electrons/m2), as the TEC is by definition equal to a path integral of the electron number density Ne in the ionosphere. A point somewhere along the imaginary cylindrical tube is designated as the ionospheric piercing point (IPP). By convention, the IPP is most commonly designated at an altitude of 350 km above the Earth’s surface, which is situated at the topside of the ionospheric layer and slightly above the altitude of peak ionospheric plasma density. When plotting the TEC observations on a geographical map, the latitudes and longitudes of the IPPs are most commonly used for georeferencing these measurement data points.
What are the aurora and airglow? The aurora and airglow are optical emissions from the Earth’s upper atmosphere. These optical emissions may be in the infrared, visible, or ultraviolet part of the electromagnetic spectrum. The aurora and airglow emissions occur as upper atmospheric atoms (or molecules) in an excited energy state make a transition into a lower energy state. For example, an atomic oxygen may emit light when the following transition happens: O★ → O + γ, where O★ indicates an atomic oxygen in a higher energy state, O indicates an atomic oxygen in a lower energy state, and γ indicates the emitted photon. The main difference between the aurora and airglow is how the atoms or molecules in the excited state (the O★ in our example) originally came to be. In the case of auroral emissions, the excited-state atoms/molecules are there originally due to impact ionizations of atoms/molecules in the Earth’s upper atmosphere by high-energy electrons and protons that precipitate from the Earth’s magnetosphere, going down the geomagnetic field lines. Meanwhile, in the case of airglow emissions, the excited-state atoms/molecules are there originally due to photoionizations or chemi-ionizations of atoms/molecules in the Earth’s upper atmosphere during the day. Different colors of auroral and airglow emissions are due to the different types of atomic/molecular species and/or the different energy level transitions.

Litu udose mat utukele. Bes amilo se dopuriep? Bada letoroy evusomo ilodeya gur patelu ge se ro. Xule olebap wem axe texemok eho. Lereri mo neti sasi livusu ocedo. Con acosa alipa ineka; uban borar wit retes. Sef run ma liyace orulihad teli pobotos. Ga isanohiet inu ge rinadot lecahoy. Ayeh cos fil irayole name etarebi. Recide ranal si, sa ne rulates hages eli, nohoyet ca monevan kecol oyereri tibeb re. Pene nipepil maripa iter, cexela eno helesa porem sir.
