Development and evaluation of airborne microwave refractometer for studies on atmospheric tropical boundary layer radiorefractive index [PDF]

Annales Geophysicae, 1994
Observations of high-resolution data on radio refractivity were obtained by the airborne microwave refractometer over the Indian sub-continent (a tropical country) from 1971 to 1988. Detailed vertical and horizontal distributions of radio refractivity

Preliminary Assessment of BDS Radio Occultation Retrieval Quality and Coverage Using FY-3E GNOS II Measurements

Remote Sensing, 2023
The FengYun-3E Global Navigation Satellite System (GNSS) occultation sounder II (FY-3E GNOS II) was launched on 5 July 2021. For the first time, based on the new GNOS II sensor, this mission realizes radio occultation (RO) and reflectometry observations ...

Principal Component Analysis Of The Worldwide Oceanic Rf Refractivity Database

, 2015
Refractivity causes ducting of transmitted RF signals over the ocean. There is apparent redundancy in the RF refractivity database for oceanic environments with weather conditions that negatively impact RF systems.

Refractivity and refractivity gradient estimation from radar phase data: a least squares based approach [PDF]

Tropospheric refractivity, related to temperature, pressure, and humidity, is an interesting parameter for weather analysis, prediction, and study of climate trends. It has been shown to be useful for the detection and forecast of convective events.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Quality assessment of YUNYAO radio occultation data in the neutral atmosphere [PDF]

Atmospheric Measurement Techniques
Global Navigation Satellite System (GNSS) radio occultation (RO) data are an important component of numerical weather prediction (NWP) systems. To incorporate more GNSS-RO data into NWP systems, commercial RO data have become an excellent option. Tianjin
