A new hyperspectral radiometer integrated ai automated networks of water and land bidirectional reflectance measurements for satellite validation.
Networking of automated instruments on unmanned platforms, e.g. AERONET-OC and RADCALNET, has proved to be the most effective way to provide validation data for Copernicus optical missions. The re-use of data from each site for many optical missions (S2, S3, PROBA-V,MODIS,VIIRS,L8,Pléiades,ENMAP,PRISMA,SABIAMAR,etc.) gives a huge economy of scale. The existing AERONET-OC and RADCALNET networks are based on multispectral instruments, which are expensive to acquire and require modelling associated uncertainties to cover all spectral bands of all sensors. Recent advances in opto-electronics facilitate the use of miniaturized hyperspectral spectrometers, with reduced price. Industrial production of video surveillance cameras greatly reduces the price of pointing systems for scientific instruments. Improved LEDs can provide a stable light source for relative calibration and continuous autonomous monitoring of radiometers. Webcams (for remote inspection of instruments and maintenance support) and data transmission have become cheaper allowing reducing the running costs and improving the reliability of autonomous instrument systems. The objective of the HYPERNETS project is to develop a new lower cost hyperspectral radiometer and associated pointing system and embedded calibration device for automated measurement of water and land bidirectional reflectance. The instrument will be tested in a prototype network covering a wide range of water and land types and operating conditions. Quality controlled data with associated uncertainty estimates will be provided automatically for the validation of all optical satellite missions. Preparations will be made a) for the new instrument design (and associated calibration service) to be commercialized with an expected lifetime of at least 10 years and b) for the networks to be further expanded to become the main source of surface reflectance validation data for all spectral bands of all optical missions for at least the next 10 years.

Physics of extreme massive stars
Massive stars are extreme cosmic engines, enriching their environments with chemically processed material throughout their entire life-time, and triggering star and planet formation. Despite their importance for the cosmic evolution, their evolutionary path up to their deaths as spectacular supernova explosions is most uncertain due to the lack of precise knowledge of the physical mechanisms behind mass eruptions. We wish to establish a multidisciplinary, international network of researchers from Europe, Asia, and South America with expertise in a variety of disciplines, and with background in both theory and observations.
Our ultimate goal is to enlighten the processes that trigger mass loss in massive stars during extreme phases of their evolution. We will develop cutting-edge numerical codes suitable to describe the chemical and dynamical evolution of the stars, their winds, and their large-scale environments. In addition, we will initiate global observing campaigns utilizing facilities at major renowned observatories in combination with our national facilities, and exploit public archives from ground-based and space missions to acquire an outstanding set of urgently needed highest quality data. Confronting predictions from the numerical models with the observations will empower us to derive the first extensive and comprehensive set of precise physical parameters.
The acquired results will significantly enhance our knowledge and lead to major advancements in all related fields. The bulk of exchanges will be undertaken by Early Stage Researchers and young Post-docs, who will be educated and trained in modern observing and data analyzing techniques and in high-performance computation, equipping them with excellent skills for their future careers. We will organize schools and workshops to share knowledge and to communicate and disseminate our results, which will be major breakthroughs and support the leading role of Europe in Astronomy.

Metrology for Earth observation and climate
The Earth’s climate is changing although the scale of impact to society remains uncertain and with it government’s ability to confidently take necessary mitigation/adaptation in a timely manner. A key limitation is the performance of forecast models and the quality of the data that drive them. Remote sensing from space, is the major means of obtaining the global data needed. The harshness of launch and environment of space severely limits accuracy and traceability. This project will improve pre-and post-launch calibration/validation (Cal/Val) of observations (land, ocean and atmosphere) to enable trustable information on the state-of-the-planet to be delivered to policy makers. The overall aim of the project is to contribute to the establishment of the necessary metrology infrastructure, tailored to climate needs in readiness for its use in climate observing systems.
