Level 2 Product Definitions
Contents 1 Specification of Level 2 Products and Auxiliary Products 9 External Field and Current Systems 10 Precise Orbit Determination Products 11 Magnetic Forcing of the Upper Atmosphere

C  derived from Comprehensive Inversion 
D  derived from dedicated chain 
F  Fast Track product 
E  Extended, only applied for extended lithospheric field maps (MLI_SHA_2E) 
_  Only one chain has been indentified to lead to this product type 
a  Product derived from candidate chain a (only applied for mantle conductivity products  derived in the frequency domain) 
b  Product derived from candidate chain b (only applied for mantle conductivity products  derived in the time domain) 
For example, the intermediate product of the spherical harmonic model of the core field derived from CI is named MCO_SHAi2C, and the final product of the spherical harmonic model of the core field derived from dedicated inversion is named MCO_SHA_2D. The product of Eastward Electric Field derived from Swarm C is called EEFCTMS_2F. The Auxiliary data product for the KP index is called AUX_KP__2_.
Product classification
Different product types exist in the Level 2 processor.
Level 2 products
Three Categories have been defined in [AD12]. Each Level 2 product is attributed to one of these categories.
CAT1: Complex algorithms contributing to the generation of a Level 2 product of the various sources of the Earth's magnetic field, of thermospheric products, and for Precise Orbit determination. The generation of CAT1 products require interaction with experienced scientists. The products will be processed by SCARF, and will be distributed by ESA.
CAT2: Algorithms leading to a Level 2 product with minimum delay with respect to the generation of the corresponding Level 1b data. The generation of CAT2 products is designed to run automatically. The CAT2 products will be generated and distributed by ESA.
Intermediate and final products
Some Level 2 products are further characterized by product types. These are:
 Intermediate products are Level 2 products which are independently validated before their release to final Level 2 products. Intermediate products are delivered to PDGS together with an intermediate validation report. An intermediate validation report exists to each chain that submit an intermediate product. The intermediate validation report product name is FFF_VALi2z, e.g., MCO_VALi2C.
 Final Level 2 products are validated intermediate products or products which are released on Fast Track including internal quality check (Fast Track Products). Only Final products are distributed to the end users.
Candidate products
For all magnetic field products and the 3Dmantle conductivity product two or three different candidates can be identified reaching to the same product quantity. For all magnetic field products, the candidates are derived in the Comprehensive Inversion Chain or in Dedicated Inversion Chains or as Fast Track products. This identification is indicated by the last character in the product name C, D or F (see also section 2).
In the case of 3D mantle conductivity model, the two candidates differ in that they are derived in the frequency domain or in the time domain. This differentiation, a or b, is indicated by the last character in the product name. All other products have only one candidate.
Fast Track products
Fast Track products have no intermediate stage. The validation is performed by means of an internal quality check in the algorithms of each of these products, and the quality of the product is provided, e.g., by a quality flag. Fast Track products are released without a validation report.
Three CAT1 magnetic products will be derived on Fast Track (Euler angles, core field model, magnetospheric model). All CAT2 products are Fast Track products. For all Fast Track products, the last letter of the product name is F (see section 2).
Final validation reports
For nonFast Track products a validation report is required when releasing the intermediate products to the final product stage. A final validation report is provided for each product chain, e.g., MCO_VAL_2D, for the final validation report for the dedicated chain for the core field model. The input of the final validation report is the intermediate product, the intermediate validation report and auxiliary products.
The intercomparison between products of two chains in one product family (e.g., MCO_SHA_2D and MCO_SHA_2C), will be released in one validation report called, e.g, MCO_VAL_2_.
Validation report products exist for following product families: Euler angles, core field models, lithospheric field models, ionospheric models, magnetosphere models, 1Dmantle conductivity (mantle conductivity model and Cresponse), 3Dmantle conductivity (mantle conductivity model and Cresponse maps), precise orbit determination and thermospheric winds and density.
Final validation reports are Final Level 2 products.
Quick Look reports
One QuickLook report exists for following data groups:
 Magnetic field measurements (MAG_QL__2_)
 Ionospheric plasma parameters from EFI (EFI_QL__2_)
The QL reports are provided as PDF files.
Auxiliary products
Auxiliary products are necessary prior or during processing of high precision Swarm Level 2 products but do not result from the Swarm L0 or L1b processor. Auxiliary products are further classified in auxiliary models and auxiliary data.
For auxiliary products that are needed in CAT1 as well as in CAT2 chains, two different products are defined. The acquisition of auxiliary products for CAT2 products lies in the responsibility of PDGS in the course of the mission. The name of all CAT2 auxiliary products end with the letter F – Fast track.
Level 2 product selection
All Level 2 Cat1 FastTrack, QuickLook, Orbit Determination, and Upper Atmosphere products (see Table below) will be transferred from the product creator (L2PS) to PDGS at ESA for immediate dissemination to the user community.
Level 2 Cat1 magnetic products (all non FastTrack magnetic field model and mantle conductivity products, see Table 2) are subject to independent validation by BGS. The validation reports together with the model products are further subject to an independent review performed by the product creator (L2PS), external experts and the Agency. Based on this review, accepted Level 2 products will be transferred from BGS to PDGS for dissemination to the user community.
All Level 2 Cat2 product are produced and distributed by PDGS and are not subject to external validation.
This section provides an overview about all L2 product, intermediate (Table 1) and final (Table 2), and auxiliary products (Table 3). Each product is described in detail in sections 5  13.

FAC_TMS_2F (FACdual)
Product identifier  FAC_TMS_2F  
Definition 
Time series of fieldaligned and radial current densities along the orbit using the dualsatellite method. Fieldaligned current (FAC) density is derived by the multiplication of the radial current (IRC) density with the inclination angle of the geomagnetic field. The fieldaligned current density can only be calculated at latitudes, where the magnetic field is well inclined, i.e. I > 30°. Near the magnetic equator for magnetic inclination angles I < 30° FAC values are set to NaN. The radial current density can be provided along the whole orbit, except for latitudes θ>86° (near poles), where both FAC and IRC values are set to NaN. Note that the magnetic field data used for the dualsatellite method is lowpass filtered with a 3dB cutoff period of 20 s (corresponding to a wavelength of 150 km). This step is indispensable because the lateral distance between Swarm A and Swarm C has to be taken into account.

Notes 
The density data is derived from the ACCxPOD nongravitational acceleration component along the spacecraft Xaxis. The following processing steps have been performed:  Modelled radiation pressure accelerations have been subtracted from the full nongravitational accelerations, to arrive at aerodynamic accelerations. Because the Kalman filter approach results in a smoothed representation of true accelerations, the radiation pressure model output has been smoothed as well, in order to avoid density jump artefacts at eclipse transitions.  The resulting aerodynamic accelerations are converted into densities, using an aerodynamic model based on a panelised representation of the satellite. The gassurface interaction is based on diffuse reflection, and an energy accommodation coefficient of 0.93 is used.  The densities are multiplied by a factor of 1.32, to compensate for the observed difference in scale between the panelised aerodynamic model, and an aerodynamic model based on a more accurate representation of the geometry of the Swarm satellites. The more accurate model will be implemented in a future updated version of the data.  The density_orbitmean field contains the mean density, taken over one orbital period, for each time step.The orbital period in seconds is provided as metadata in the CDF file. At high altitude and low solar activity, the errors inherent in the radiation pressure model and acceleration determination using GPS data can become significant compared to the magnitude of the acceleration signal. This can result in large density errors and even negative densities. Users are advised to use the orbit mean densities in those conditions.

Notes 
The 3 hourly KP index values are published with a delay between 1 and 3 hours with respect to the hour of the day.
All the three hours KP index values of the day not yet available at the time of the download are filled with "99". E.g downloading the data after the 7.30 p.m a possible value of the Kp index is 1710102010999999 . Please note that all the 8 i2 value have been filled. 1328 8i2 3hourly Kp indices (03, 36, 69, 912, 1215,1518, 1821, 2124 UT) The Kp daily sum is computed only in case the three hourly KP index covering the whole day are available (all 8 i2 different from "99"). In case of lack of data the Kp daily sum is not computed and the related 3 columns are filled white space. E.g " " 2931 i3 Daily Kp sum, expressed to the nearest third of a unit (supplied only for tradition, use Ap scientific purposes!) The 3 hourly Ap index are computed together with the Kp index so the related column will be filled with the Ap values only if the Kp related to the same 3 hour column is available. E.g downloading the data after the 7 p.m a possible value of the Ap index is " 6 4 4 7 4". The value not already computed will remain empty, i.e. filled with spaces. 3255 8i3 3hourly ap indices (03, 36, 69, 912, 1215,1518, 1821, 2124 UT)

The close correlation between (Rz)12 and (F10.7)12 is used to derive the (Rz)12 indices. An IG index of 111 indicates that no IG values are available for the time period. In this case a correlation function between (IG)12 and (Rz)12 is used to obtain (IG)12.
