		Barographs use one or more aneroid cells acting through a gear or lever train to drive a recording arm that has at its extreme end either a scribe or a pen.
		Barographs are required by the (additional info and facts about FAI) FAI to record certain tasks and record attempts associated with (Aircraft supported only by the dynamic action of air against its surfaces) sailplanes.
		These are not only less expensive than mechanical barographs but they may also offer both greater recording length and the ability to perform further data analysis on the captured data including automated use of the data to forecast the weather.

		Mechanical barographs have a drum on which a pressure sensitive paper, piece of foil, or paper for an ink tracing, depending on the type of barograph, can be mounted.
		The purpose of the seal is to be sure that the barograph has not been opened during the time that the barograph leaves the official observerâs hands before the flight, and the time it is once again in the observerâs hands, after the flight.
		When using an electronic barograph, be sure that the directions for the official observer's mark (in lieu of the initials on the drum-type barograph) are followed exactly.

		The recording barometer, or "barograph" shown above is a barometric pressure indicator that records the barometric pressure on paper chart.
		Typical barometric readings on the barograph hover around the white areas of the chart as indicated below in a 2-week run in the spring of 2004.
		The Ivan barograph showed a deeper low pressure dip than Frances and brought stronger winds to campus creating much more extensive electrical power outages.

	Skydiving Barograph
		The first barograph did not have a display, but was designed to print a paper copy of the logged time and freefall speeds to a small printer after the jump, since a portable computer was not available to me and drop zones did not have computers available to use.
		Since a barograph determines freefall speed based on pressure measurement as opposed to actual airspeed measurement, what must be kept in mind is that this length of time is actually the time required to begin falling straight down rather than the time it takes to get to terminal velocity.
		Other barograph jumps will be made in the future for the purpose of "filling out" the freefall speeds chart so that it can be used as a guide to jumpsuit selection, video partner and team personnel selection, load organizing, and as a general guide to skydivers attempting to fall at the same rate.

		The rule on continuous observation is that an O/O on the ground should be within 1000m vertically and 2000m horizontally from the glider.
		For Gold or Diamond Height a "Gain of Height Certificate" or a clear copy of a valid calibration chart is required and the barograph should be calibrated by an approved instrument facility either within 12 months before or 1 month after the flight.
		With a trace barograph the O/O would mark the trace to confirm flight, details, goal and their name and O/O number.

	Barograph
		The instrument currently used to measure atmospheric pressure for the NPL on-line barograph is a good-quality, commercially available resonant pressure sensor.
		The performance of all instrumentation changes with time and indeed the sensors used in the NPL on-line barograph, despite being state-of-the-art devices, have changed significantly since being installed and continuity of performance and accuracy is only achieved by regularly recalibrating the sensors and updating the calibration correction data applied by the host computer.
		To the best of our knowledge, the NPL on-line barograph is unique inasmuch as it provides a fully traceable pressure measurement, with a properly calculated uncertainty, and also allows historical data to be displayed both graphically and digitally.

		To make a record of the air pressure and how it's changing, and aneroid is connected connected with a device that records air pressure, making it an aneroid barograph.
		The aneroid barograph consists of a slowly rotating cylinder with paper on it that can give up to a week's worth of air pressure records before new paper is needed.
		As you can see in the graphic above, a pen at the end of a lever attached to the aneroid moves up and down according to pressure changes and records the pressure on the paper wrapped around the cylinder.

		Because the amount of movement that can be generated by a single aneroid is miniscule, up to seven aneroids are often stacked "in series" to amplify their motion.
		Nowadays, mechanical recording barographs have commonly been superseded by electronic weather instruments that use computer methods to record the barometric pressure.
