ISLSCP II: Near Surface Meteorology Parameters at 1 degree spatial resolution (1986-1995)
Abstract
The International Satellite Land Surface Climatology Project, Initiative II (ISLSCP II) is a follow on project from The International Satellite Land Surface Climatology Project (ISLSCP). ISLSCP II had the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP).
This dataset contains:
*precipitation
*temperature
*diurnal temperature range
*wet-day frequency
*vapour pressure
*cloud cover
*ground frost frequency
The data are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public.

| Title | ECMWF reanalysis output for the ISLSCP-II project |
| Abstract | The ECMWF (European Centre for Medium-range Weather Forecasts) near-surface data set for the ISLSCP Initiative II data collection has been derived from the ECMWF 40-year reanalysis, or ERA40 (Simmons and Gibson, 2000), covering the years 1957 to 2001. The purpose of ERA40 is to produce an objective analysis of the atmosphere making optimal use of a wide range of observing systems. A recent version of the ECMWF Numerical Weather Prediction system (cycle 23r4) is used for the entire analysis period. The advantage of re-analysis over operational analysis is that no system changes occur that might affect the analysis products, although there are significant changes in the observations |

| Title | NCEP reanalysis output for the ISLSCP-II project |
| Abstract | The analysis increment for the NCEP/DOE AMIP-II reanalysis is six hours, and output data are routinely reported every hour or six hours. In order to satisfy the ISLSCP-II requirement for 3-hourly data, twice daily 36 hour forecasts were made and hourly output were obtained from the 24-36 hour forecasts. The 24-36 hour forecasts were chosen to minimize "spin-up/spindown" problems. The one-hour data were later combined to produce 3-hourly data. Time averaging was performed on the native reanalysis grid. For the 3-hourly and the monthly-3- hourly data, the hour in the file name refers to the end of the 3-hour period. For example, 03Z refers to the value at 03Z (for instantaneous data) or the average over the preceding period 00Z- 03Z (for the flux fields and snow cover fraction). |
