[arts-users] A question about how to input multiple shapes of single scattering particles into the one same profile

[li zhuoyang]

Dear all
 
Hello!
 
1. I want to input multiple shapes of single scattering particles from ARTS 
SSDB(single scattering database) into an input profile for microwave 
simulation, such as 8ColumnAggregate and 6BulletRosette. But I found that when 
I used the ScatElementsPndAndScatAdd method, scat_ Data_ Files can only input a 
scat_data.xml file with one particle size. If using a matlab program named 
demo_ssp4arts.m in DataInterfaces to convert the scattering data of 
8ColumnAggregate_Id8 particles in the database from nc format to the format 
used internally by ARTS, an error message will generate: XML parse error: Tag 
<SingleScatteringData&gt; expected but <Array&gt; found.I think that this means 
an array of SingleScatteringData of different sizes can??t be read by the 
method of ScatElementsPndAndScatAdd .How can I achieve the operation of 
inputting multiple shapes of single scattering particles into the one same 
profile in this case? Why the 8ColumnAggregate_scat_data.xml file generated by 
demo_ssp4arts.m can??t be read by the method of ScatElementsPndAndScatAdd?
 
2. I noticed that the scat_data.xml provided in the 
controlfiles2.5.11/artscomponents/psd/testdata/ is formed by two types of 
particles, one is ??Liquid sphere?? and the other is ??Hexagonal column 
aggregate??. The scat_data.xml generated by demo_ssp4arts.m can only have 
single scattering data arrays of different sizes for particles of the one same 
shape. May I ask how can I also create multi-shaped scattering data like 
??scat_data.xml?? in the 
controlfiles2.5.11/artscomponents/psd/testdata/scat_data.xml?
