4.54.1 SCIA LV1 RD MDS
Identifier SCIA LV1 RD MDS
Purpose read MDS of one state from a SCIAMACHY level 1b product
Usage nr mds = SCIA LV1 RD MDS( fd, clus mask, state, &mds );
Input FILE *fd : (open) stream pointer
ulong64 clus mask : mask for cluster selection
In/Output struct state1 scia *state : structure with States of the product (E.22)
Output struct mds1 scia **mds : structure for level 1b MDS records (E.31)
Returns number of level 1b MDS read (unsigned int),
error status passed by global variable “nadc stat”
Comment This routine allocates memory for the following variables:
sat flags, red grass, glint flags, geoN/geoL/geoC, lvl0 header,
int pmd, polV
and depending up on the cluster configuration:
clus[].sig, clus[].sigc
4.54.2 SCIA LV1C RD MDS
Identifier SCIA LV1C RD MDS
Purpose read SCIAMACHY level 1c MDS
Usage nr mds = SCIA LV1C RD MDS( fd, clus mask, state, &mds );
Input FILE *fd : (open) stream pointer
ulong64 clus mask : mask for cluster selection
In/Output struct state1 scia *state : structure with States of the product (E.22)
Output struct mds1c scia **mds : structure for level 1c MDS (C.11)
Returns number of level 1c MDS read (unsigned int),
error status passed by global variable “nadc stat”
Comment This routine allocates memory for the following variables:
pixel ids, pixel wv, pixel wv err, pixel val, pixel err,
geoN/geoL/geoC
4.54.3 SCIA LV1C RD MDS PMD
Identifier SCIA LV1C RD MDS PMD
Purpose read SCIAMACHY level 1c PMD MDS
Usage nr mds = SCIA LV1C RD MDS PMD( fd, state, &pmd );
Input FILE *fd : (open) stream pointer
struct state1 scia *state : structure with States of the product (E.22)
Output struct mds1c pmd **pmd : structure for level 1c PMD MDS (C.12)
Returns number of level 1c PMD MDS read (unsigned int),
error status passed by global variable “nadc stat”
Comment This routine allocates memory for the following variables:
int pmd, geoN/geoL/geoC
