New constraints on Northern Hemisphere growing season net flux
[1] Observations of the column-averaged dry molar mixing ratio of CO2 above both Park Falls, Wisconsin and Kitt Peak, Arizona, together with partial columns derived from aircraft profiles over Eurasia and North America are used to estimate the seasonal integral of net ecosystem exchange (NEE) between the atmosphere and the terrestrial biosphere in the Northern Hemisphere. We find that NEE is 25...
متن کاملNorthern Hemisphere tropical cyclone activity
[1] Recent historical Northern Hemisphere (NH) tropical cyclone (TC) inactivity is compared with strikingly large observed variability during the past three decades. Yearly totals of the combined active-basin NH accumulated cyclone energy (ACE) are highly correlated with boreal spring seasurface temperature (SST) in the North Pacific Ocean and are representative of an evolving dual-gyre, trans-...
متن کاملChanging Northern Hemisphere Snow Seasons
Spatial and temporal patterns in the onset, offset, and length of the snow season across Northern Hemisphere continents are examined for the period from 1967 to 2008. Full snow seasons (FSS) and core snow seasons (CSS) are defined based on the consistency of snow cover within a location over the course of the cold season. Climatologically, the seasonal onsets of FSS and CSS progress more rapidl...
متن کاملMars- Northern hemisphere slopes and slope distributions
We investigate slope distributions in the northern hemisphere of Mars from topographic profiles collected by the Mars Orbiter Laser Altimeter. Analysis of the region from about 12øS to 82øN, over diverse geologic units, indicates that the range of regional-scale slopes is small, generally < 3 ø. Surface smoothness is most distinctive in the vast northern hemisphere plains, where slopes are typi...
متن کاملSTIS Flux Calibration
The low dispersion STIS spectrophotometric flux calibration must account for all instrumental non-linearities and all changes in sensitivity with time and temperature. An empirical algorithm for CCD Charge Transfer Efficiency (CTE) is presented along with the wavelength dependent sensitivity changes. Precise STIS spectrophotometry includes corrections for CTE losses as large as 20% for faint si...
