The region boundaries described below have been updated to exactly match UAH region boundaries. My thanks to Dr. John Christy of UAH for supplying the boundary information.
A new feature in the Climate scientist Starter Kit v2.0 is regional data. For all ISCCP data products, the following regions will be supported:
- Northern Hemisphere (north of Equator)
- Southern Hemisphere (south of Equator)
- Tropics (70˚ from South Pole to 110˚ from South Pole)
- Northern Extra Tropics (110˚ from South Pole to 120˚ from South Pole)
- Southern Extra Tropics (70˚ from South Pole to 60˚ from South Pole)
- North Pole (120˚ from South Pole)
- South Pole (60˚ from South Pole)
This provides data similar to the UAH temperature data products and allows for analysis on the local level in addition the global level already supported. The ISCCP data in v1.5 includes Clouds and Water Vapor. In v2.0 we'll see the introduction of additional ISCCP data, which wil be discussed in a future post.
Splitting the ISCCP data into regions was done based on the girding of the data product. For equal area grids, the ISCCP data product covers the Earth using the method shown in the diagram below.
This grid was used to create the regional data products.
Cosmic rays will also have regional coverage. This will be done by adding the readings from additional monitors around the globe.
The graph below shows the v2.0 water vapor values as broken up by region.
Normalized Data Included
Normalized data is also included for the regional data. The graph below shows normalized North Pole Water Vapor along with normalized Solar Ephemeris.
