Hiroshi Tanimoto, Director of the Earth System Division at the National Institute for Environmental Studies (NIES), Japan, and Astrid Müller together with their international research team, have developed a new method to evaluate satellite observations of XCO2 over open ocean areas, which are currently inaccessible through established validation network sites. In the new approach, a reference CO2 dataset is formulated by combining cargo ship and passenger aircraft observations which were conducted in cooperation with operators of the private sector.
(Background)
After the Paris Agreement entered into force, commitment to reduce greenhouse gas emissions are being expedited. CO2 is the most important anthropogenically produced greenhouse gas. Emissions due to fossil fuel combustion and cement production have caused an accelerated increase of atmospheric CO2 to more than 410 ppm in 2020 since the 1950s (Dlugokencky and Tans, 2021).

AC/DC convection cooled sealed power supplies for harsh environments
Bel Power Solutions has released the ABS400/MBS400 Series of convection cooled power supplies which are sealed and fully potted, providing IP66/67 ingress protection and fit 1U applications. These devices can be mounted for conduction or convection cooling and are rated at 300W in still air and 400W with conduction through the optional heat sink.
The ABS400 Series offers a wide universal AC input range of 90-264VAC, giving up to 400W of output power in a single output of 12, 24, 36, or 48VDC and are provided in a 3.27 x 8.34 x 1.65 (83mm x 212mm x 42mm) form factor giving 12 and 5VBS standby outputs and a full set of protection features. This series also provides control signals including Power Good (Power OK), Remote On/Off (PS ON), and Remote Sense (+RS). Ideal applications comprise video wall displays and entertainment lighting, industrial and process control, telecommunications, laboratory and test and meas
