Version 2 of the EUMETSAT OSI SAF and ESA CCI sea-ice concentration climate data records
We introduce the OSI-450, the SICCI-25km and the SICCI-50km climate data
records of gridded global sea-ice concentration. These three records are
derived from passive microwave satellite data and offer three distinct
advantages compared to existing records: first, all three records provide
quantitative information on uncertainty and possibly applied filtering at
every grid point and every time step. Second, they are based on dynamic tie
points, which capture the time evolution of surface characteristics of the
ice cover and accommodate potential calibration differences between satellite
missions. Third, they are produced in the context of sustained services
offering committed extension, documentation, traceability, and user support.
The three records differ in the underlying satellite data (SMMR & SSM/I
& SSMIS or AMSR-E & AMSR2), in the imaging frequency channels (37 GHz
and either 6 or 19 GHz), in their horizontal resolution (25 or 50 km), and
in the time period they cover. We introduce the underlying algorithms and
provide an evaluation. We find that all three records compare well with
independent estimates of sea-ice concentration both in regions with very high
sea-ice concentration and in regions with very low sea-ice concentration. We
hence trust that these records will prove helpful for a better understanding
of the evolution of the Earth's sea-ice cover.</p
City branding as economic necessity
Kvalitetno brendiranje grada je preduvjet za njihovu prepoznatljivost, kvalitetno pozicioniranje i stvaranje dodatne vrijednosti. Praksa i mnogobrojni primjeri potvrđuju ispravnost ove teze. Brendiranje gradova je nužno kako bi se pojačala konkurentnost, ostvarila veća dobit i osigurao razvoj mjesta. No ne radi se samo o ekonomskim kategorijama jer se pod razvojem mjesta podrazumijevaju i pozitivna demografska kretanja, obogaćivanje kulturnih sadržaja kao i drugih činitelja koji podižu ukupnu kvalitetu života. Izazov je to i nužnost i za gradove u Hrvatskoj kako bi bili konkurentni u oštroj tržišnoj konkurenciji.Quality city branding is a precondition for their recognazibility, quality positionig and creating of added value. Practice and numerous examples confirm correction of this theses. City branding is necessary to enhance concurence, gain bigger profit and ensure place development. But this is not only about economic categories because under place development it is understandable alsto positive demographic movement, enrichment of cultural contens as well as other factors which raise total quality of life. This is as well a challenge as it is a necessity for cities in Croatia so they could be concurente in harsh economy concurence
SMOS: Objectives and Approach for Ocean Salinity Observations
International audienceSMOS (Soil Moisture and Ocean Salinity), launched in November 2, 2009 is the first satellite mission addressing the salinity measurement from space through the use of MIRAS (Microwave Imaging Radiometer with Aperture Synthesis), a new two-dimensional interferometer designed by the European Space Agency (ESA) and operating at L-band. This paper presents a summary of the sea surface salinity retrieval approach implemented in SMOS, as well as first results obtained after completing the mission commissioning phase in May 2010. A large number of papers have been published about salinity remote sensing and its implementation in the SMOS mission. An extensive list of references is provided here, many authored by the SMOS ocean salinity team, with emphasis on the different physical processes that have been considered in the SMOS salinity retrieval algorithm
