Publikováno v: Geophysical Research Letters, Vol 50, Iss 8, Pp n/a-n/a (2023)

Abstract We assessed how warm air temperatures, high solar radiation, and weak wind speeds might induce hypoxia in a shallow lake during a heat wave. We simulated bottom‐water dissolved oxygen concentrations and compared concentrations in 2022 with

Challenges of an optical pressure standard in medium vacuum measurements

Autor: Yoshinori Takei, Souichi Telada, Hajime Yoshida, Youichi Bitou, Tokihiko Kobata

Publikováno v: Measurement: Sensors, Vol 22, Iss , Pp 100371- (2022)

Optical pressure standards (OPS) using Fabry-Perot (FP) cavities can measure a wide pressure range with high accuracy. National metrology institute of Japan (NMIJ) is developing an OPS for the pressure range of 1 Pa–100 kPa. In this study, the targ
