  • Pronóstico Numérico de Olas (SMN)

    La altura significativa se infiere en el modelo a partir de la energía total de las olas. Se asemeja a la altura característica que un observador experimentado estima visualmente en un campo de olas y es la medida representativa del campo más utilizada. Sin embargo, se debe destacar que las olas individuales pueden exceder la altura significativa (idealmente algo más del 13 % de las olas) y aun en condiciones normales, alguna ola individual podría duplicar esta altura. La dirección del pico es la dirección media en las frecuencias que contienen la máxima energía y es cercana, en general, a la dirección del máximo. El período del pico de energía o período dominante es el correspondiente a las frecuencias que contienen la máxima energía. Todas las alturas se expresan en metros.

  • Tidal Glossary

    Terms that are often used in Tidal Science.

  • Compute Sunrise, Transit, Sunset and Twilight Times

    The transit time of a celestial body refers to the instant that its center crosses an imaginary line in the sky - the observer's meridian. It's represents the time at which the body is highest in the sky on any given day: the transit of the Sun is local solar (sundial) noon. At the twilight time in the absence of moonlight, artificial lighting or adverse atmospheric conditions, the illumination is such that large objects may be seen but no detail is discernible. The brightest stars and planets can be seen and for navigation purposes at sea, the sea horizon is clearly defined. More definitions (Geoscience Australia).

    • Sea (or wind) waves are generated by the local prevailing wind and vary in size according to the length of time a particular wind has been blowing, the fetch (distance the wind has blown over the sea) and the water depth.
    • Swell waves are the regular longer period waves generated by distant weather systems. There may be several sets of swell waves travelling in different directions, causing a confused sea state.
    • Combined sea and swell describes the combined height of the sea and the swell that mariners experience on open waters. The height of the Combined sea and swell refers to the average wave height of the highest one third of the waves. Combined sea and swell is also known as total wave height, or significant wave height. Some waves will be higher and some lower than the significant wave height. The probable maximum wave height can be up to twice the significant wave height.

    TEC Disturbance Index This index is defined as the mean deviation of the current conditions for the Total Electron Count (TEC) in the ionosphere from a 15-day running median reference data. An index of 1.5 mean there is a deviation of 150% between the current and the average TEC values. It is representative of the deviation of current ionospheric conditions from those expected by an usual GPS receiver. This deviation can cause a position error if it remain uncorrected. For the real GPS position errors refer to the L1 map below.

    S4 Index Ionospheric scintillation occurs when a radio frequency signal traverses a region of small scale irregularities in electron density in the ionosphere. This is a rapid fluctuation of radio-frequency signal amplitude. The S4 Index quantified this amplitude scintillation with a measure of the short timescale fluctuation in the signal to noise of a transmission. Values over 0.6 indicate strong scintillation which can cause loss of lock on a GPS signal. A scintillation index below 0.3 is unlikely to have any affect on GPS.

    • GPS: L1 Ionosheric Positioning Error

      The ionosphere is a significant source of error in satellite navigation systems, such as GPS. In ordinary operation the position of a GPS receiver is estimated by measuring the time delay between a radio signal transmitted from each satellite and the reception of that signal at the receiver. Assuming a constant speed of light, this time delay can be converted to a receiver-satellite distance. By comparing the distance to multiple satellites a GPS receiver can determine its three dimensional position. The ionosphere disrupts this approach since the GPS radio signal is slowed by the presence of free electrons, causing an additional time delay and hence an error in the distance to each satellite. The greater the total number of electrons (Total Electron Count, or TEC) on the signal path, the greater the time delay.
      This near-real-time map shows the estimated GPS positioning error, in metres of L1, resulting from the difference between the GPS broadcast Klobuchar model of ionospheric delay and the best current estimate of 'true' ionosheric delay, as observed by SWS. It is therefore representative of the ionospheric contribution to GPS position error for single-frequency GPS, which at mid-latitudes typically ranges between 1 and 5m. Both enhancements and depressions of the ionosphere can result in reduced GPS positioning accuracy. The map shows colour contours of position error at GPS L1 (ie single frequency), in units of metres.

    • Introduction to HF Radio Propagation

      There can be many reasons why an HF signal may not reach the intended recipient, including solar flares, ionospheric storms, geomagnetic storms, equipment faults and the choice of frequency. Summary: 1. The ionosphere - 2. HF communications - 3. Effects of solar events on HF communications. Also in HTML.

    • HF Propagation Conditions

      These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts (More information about HF Communications Problem).
