SMEX05 Meteorological Network Data: IowaEntry ID: NSIDC-0455
Abstract: Notice to Data Users: The documentation for this data set was provided solely by the Principal Investigator(s) and was not further developed, thoroughly reviewed, or edited by NSIDC. Thus, support for this data set may be limited. This data set includes the meteorological data collected as part of the Soil Moisture Experiment 2005 (SMEX05) in the Walnut Creek watershed area of Iowa, USA from 01 ... June 2005 through 17 July 2005. The total volume of this data set is approximately 14 megabytes. Data are provided in comma-delimited ASCII text format and are available via FTP. The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) is a mission instrument launched aboard NASA's Aqua satellite on 04 May 2002. AMSR-E validation studies linked to SMEX are designed to evaluate the accuracy of AMSR-E soil moisture data. Specific validation objectives include: assessing and refining soil moisture algorithm performance; verifying soil moisture estimation accuracy; investigating the effects of vegetation, surface temperature, topography, and soil texture on soil moisture accuracy; and determining the regions that are useful for AMSR-E soil moisture measurements.

ISO Topic Category
Quality Because stratospheric ozone at any time is determined largely by meteorological transport forcing conditions (rather than by chemistry constraints), this indicator is expected to have substantial interannual variability, and care is needed in its interpretation.
Trends in ozone will be analysed for signs of the success of the Montreal Protocol in phasing out ozone depleting substances (ODSs). However, the life-time of ODSs in the atmosphere is in the order of decades, and so the global concentration of ozone is expected to continue to fall until after the turn of the 20th century. Full recovery of the ozone layer will require some decades beyond the time that the supply and emission of ODSs is stopped (Fraser 1997). Values provided in temporal coverage are approximate only.
