sciaL2_ascii , Version 0.94----------------------------------------------------

sciaL2_ascii is a tool for reading SCIAMACHY Level-2 products (PDS Format)to an easy to use ASCII output. Additonally, GOME Level-2 products aresupported. Readable products are: - Near-Real-Time (NRT) : SCI_NL__2P....N1 - Offline products (OL) : SCI_OL__2P....N1 (SCIA-OL/2.1 or higher) - Products for Meteo-Users : SCI_RV__2P....N1 - GOME products : ymmddhhm.lv2The programm includes a geopgraphical search modus.

Read ozon values from NRT product Oct, 29th 2002. Output (defined with -d) is a : orbit

d : center coordinates A : O3 [mol/cm2]

B : O3 error [%] C : O3 [DU]
