Abstract: In many countries, most instruments in the field of observational environmental systems do not comply with metrological requirements and meteorological recommendations, due to factors ranging from a lack of knowledge about the importance of metrological activities to the costs involved. Regionally the great challenge is to make measurements across the territory with comparable results. In this article, we present boundary conditions that make up a scenario that allows remote and online calibration of Meteorological Stations, connecting different sectors and technologies. We hope that this methodology will contribute to know the reliability of measurements in the field and meet safety measures, due to the current Covid pandemic.

Resumo: 193 Estados Membros da ONU estabeleceram 169 metas de ação global e 17 objetivos para o desenvolvimento sustentável (ODS), abrangendo as dimensões ambiental, econômica e social, de forma integrada e inter-relacionada, para serem alcançadas até 2030. A partir daí, diversas iniciativas vêm sendo abordadas para o cumprimento desses ODS. Uma delas é a partir da implementação das normas de gestão das famílias ISO, contribuindo significativamente para o atendimento dessas metas. Dentro das séries ISO existem correspondências com cada ODS. Dessa forma, a gestão e a ISO se mostram atentas às demandas atuais com alto potencial na contribuição efetiva dessas metas.

Abstract: Hydrophone calibration is one of the essential activities in a National Metrology Institute with an active ultrasound laboratory. Many methods internationally validated are available to be implemented. Differences rely on the accuracy and investment in equipment and professional skills. This work presents a review of primary hydrophone calibration procedures. The procedures described result from the search selection performed in four academic databases: PubMed Medline, Web of Science, PubMed Central, and Scopus. Using the PICO strategy, the outco’mes could be used to guide a national or primary laboratory to select the more suitable method for calibrating hydrophones.
