The expression, at the mRNA level, of carotenoid biosynthetic genes from Xanthophyllomyces dendrorhous was studied by RT-PCR. The experimental conditions for the RT-PCR assay were standardized to quantify the relative transcript levels of idi, crtE, crtYB and crtI genes. This work attempted to correlate astaxanthin production with the transcript levels of carotenogenic genes in a wild-type stra...

We have derived digital elevation models (DEMs) over the western part of the Devon Ice Cap in Nunavut, Canada, using “swath processing” of interferometric data collected by Cryosat between February 2011 and January 2012. With the standard ESA (European Space Agency) SARIn (synthetic aperture radar interferometry) level 2 (L2) data product, the interferometric mode is used to map the cross-track...

This paper gives an overview of the MIPAS Level 1B (L1B) processor whose main objective is to calibrate atmospheric measurements radiometrically, spectrally and geo-located. It presents also the results of instrument characterization done on ground and during the first years inflight. An accurate calibration is mandatory for high quality atmospheric retrievals. MIPAS has shown very good perform...

Following up on the successful NSCAT mission, the QuikScat/SeaWinds scatterometer (Qscat) provides normalized radar cross section ( o) measurements of the Earth's surface at unprecedented coverage and resolution. While originally designed for wind observation, scatterometers have proven useful in a variety of land and ice studies. To aid in the selection of regions and time periods for study, a...

The L1b processor is designed to process raw, level0, data from the RA-2 instrument to apply engineering and other corrections. From the Level 0 data (which are basically telemetry data) the Level 1b processor is applied and output the Level 1b product. In doing this auxiliary data is used. These algorithms and the parameters used in this process shall be verified and possibly tuned. Later the ...

Abstract. The Ozone Monitoring Instrument (OMI) was launched on 15 July 2004, with an expected mission lifetime of 5 years. After more than 17 years in orbit the instrument is still functioning satisfactorily and principle can continue doing so until decommissioning its platform Aura 2025. In order to datasets acquired by OMI Microwave Limb Sounder, extended up at least 2023. Actions have been ...
