Satellite and Radar

Class overview

  • Sat
  • SatPlot
  • SatManager
  • MItiff

Libraries used

  • diMItiff

Sat

Info about one satellite product (one time, all channels)

  • data
  • calibration
  • projection
  • dimensions
  • channels

SatPlot

Has one Sat object, and know how to plot it

SatManager

Parse setup
  • Product
    • filenames
    • times available (from filename)
Answer requests
  • Which times are available
  • Header information from one product (time, projection,calibration, channels etc)
  • SatPlot object from one product

MItiff

  • Static functions
  • Interface between diana and the library diMItiff
  • The library functions reads just the header or header and data into some internal structure.
  • The functions in the class MItiff puts the header info and the data into a Sat object

Setup

Current syntax

image=Radar-obs
channels= PSC_Z
sub.type = Norden_2km_dBZ
file = $(OPDATA3)/nordrad/mitiff/RRPSC_Z_DNORDIC_2000_[yyyymmddHHMM].mitiff

Some additional info about file type are needed

New syntax

image=Radar-obs
channels= PSC_Z
sub.type = Norden_2km_dBZ
type = mitiff
file = $(OPDATA3)/nordrad/mitiff/RRPSC_Z_DNORDIC_2000_[yyyymmddHHMM].mitiff

How to implement a new interface

Change SatManager
  • parse and keep type information (MItiff default)
  • call the right static function depending on type, now only MItiff functions are called
Make a new class which contains static functions which return
  • Header info
  • Palette
  • data
  • day_night (only used in the function which sets channels depending on solar height)
