Resumen
Solar global radiation, air temperature, relative humidity, and wind speed were measured
in Coronel Oviedo, Paraguay, within the path of totality of the eclipse of 3 November 1994. Global
radiation decreased gradually as the sun was being eclipsed and became negligible during the totality,
then increased to their normal values. Surface air temperature decreased significantly, about 3 ‘C, with
the lowest value occurring about 7 minutes after totality. Relative humidity, because of its dependence
on temperature, increased as a consequence of the temperature decrease. Surface wind speed decreased
gradually during the eclipse, as a result of the cooling and stabilization of the atmosphere. Although
atmospheric pressure was also measured, it was not possible to record pressure changes clearly
associated to the eclipse, since the pressure sensor was only able to detect pressure variations of at
least 1 hPa.
