The Incoherent Scatter Radar (ISR) at the European Incoherent SCATter (EISCAT) has been in operation since 1981. The transmitter and one receiver is at Tromso, Norway (69.58N, 19.23E) at the approximate apex magentic latitude of 66.4 magN, and so is often in the auroral zone. There are two other receivers for bistatic operation at Kiruna, sweden (67.87N, 20.43E) and in Sodankyla, Finland (67.37N, 26.63W). These are all UHF receivers, where a separate VHF receiver and transmitter is located at Tromso. Plots and data are available at http://www.eiscat.se/madrigal in the EISCAT node of the Madrigal Database. The contact person is Esa Turunen (esa.turunen@eiscat.se). Another possible EISCAT contact who is in charge of World-Day scheduling is Ingemar Haggstrom (ingemar@eiscat.se, 46-(980)-79155, Fax 46-(980)-79159, EISCAT Scientific Association, Box 812, SE-98128 Kiruna, Sweden). Please contact them early to confirm correct use of the ISR data and to offer co-authorship for any publications. ACKNOWLEDGMENTS: We are indebted to the Director and staff of EISCAT for operating the facility and supplying the data. EISCAT is an international association supported by Finland (SA, Suomen Akatemia), France (CNRS, Centre National de la Recherche Scientifique), Germany (MPG, Max-Planck-Gesellschaft), Japan (NIPR, National Institute for Polar Research), Norway (NFR, Norges forskningsrad), Sweden (NFR, Naturvetensckapliga forskningsradet), and the United Kingdom (PPARC, Particle Physics and Astronomy Research Council). These data for the joint GEM-CEDAR Challenge of 2011 were taken from kindat=6800, which used 3 separate positions as tau1 (20 deg elevation at the Tromso UHF site), tau2 (77.5 deg elevation at the Tromso UHF site, where the other 2 UHF sites were used to get electric field vectors), and tau8 (30 deg elevation at the Tromso VHF site). All data were over 1 minute with a fine height resolution power profile (for uncorrected Ne) at the same time as kindat 6801. We used the tau2 Tromso data with corrected Ne (in m-3), Te (as Te/Ti), and Ti (in K) in 42 altitudes from 76-674 km. Only the 34 altitudes above 100 km were retained. This experiment had better E-region coverage than F-region. The Ne data were retained if the Ne error bar was less than the Ne value. The Ti and Te data were retained if the temperature error bars were <200 K, if Te/Ti were between 0.2 and 5.0, and if Ti>500K for ht>300km. Approximately 20 1-min profiles were averaged every 20 min to improve the data quality, where the error bars were the standard deviations. If only 1 value was in the average at a particular height, it was not used in the plots or in the calculation of Nmax and TEC, but was retained in the file for completeness. The maximum Ne value (Nmax in m-3) was found in each averaged profile above 100 km at height hmax (km). If a polynomial fit could be made, Nmax and hmax were refined. The total electron content (TEC in m-2) was found above 100 km using only non-missing data (and average data composed of more than 1 value). The analyst for making these 20-min data was Barbara Emery of HAO/NCAR. year dayn moda uth glat glon hmax foF2MHz Nmax(m-3) TEC(m-2) 2006 348 1214 0.08 69.58 19.23 110.94 2.84 0.9995E+11 0.1652E+17 2006 348 1214 0.32 69.58 19.23 106.86 4.00 0.1983E+12 0.2421E+17 2006 348 1214 0.66 69.58 19.23 106.33 4.91 0.2987E+12 0.3296E+17 2006 348 1214 0.99 69.58 19.23 100.83 5.19 0.3334E+12 0.3507E+17 2006 348 1214 1.33 69.58 19.23 102.37 4.81 0.2871E+12 0.3116E+17 2006 348 1214 1.67 69.58 19.23 102.84 4.25 0.2239E+12 0.2959E+17 2006 348 1214 2.00 69.58 19.23 103.98 3.91 0.1896E+12 0.2500E+17 2006 348 1214 2.33 69.58 19.23 104.92 3.52 0.1534E+12 0.1842E+17 2006 348 1214 2.66 69.58 19.23 103.72 4.33 0.2325E+12 0.2080E+17 2006 348 1214 2.99 69.58 19.23 103.40 4.39 0.2392E+12 0.1723E+17 2006 348 1214 3.33 69.58 19.23 103.92 3.46 0.1485E+12 0.1538E+17 2006 348 1214 3.66 69.58 19.23 100.91 4.57 0.2589E+12 0.1569E+17 2006 348 1214 3.90 69.58 19.23 101.14 3.72 0.1717E+12 0.1327E+17 2006 348 1214 4.40 69.58 19.23 102.27 3.56 0.1569E+12 0.1151E+17 2006 348 1214 4.66 69.58 19.23 100.77 3.90 0.1882E+12 0.1225E+17 2006 348 1214 4.99 69.58 19.23 103.24 3.73 0.1725E+12 0.1255E+17 2006 348 1214 5.32 69.58 19.23 105.80 3.27 0.1329E+12 0.1103E+17 2006 348 1214 5.64 69.58 19.23 106.80 3.08 0.1178E+12 0.1821E+17 2006 348 1214 5.99 69.58 19.23 460.80 2.46 0.7491E+11 0.1564E+17 2006 348 1214 6.31 69.58 19.23 421.26 2.36 0.6913E+11 0.1510E+17 2006 348 1214 6.69 69.58 19.23 417.39 2.18 0.5873E+11 0.1002E+17 2006 348 1214 6.88 69.58 19.23 439.59 1.80 0.4030E+11 0.9011E+16 2006 348 1214 11.12 69.58 19.23 231.37 3.68 0.1684E+12 0.2792E+17 2006 348 1214 11.32 69.58 19.23 232.86 3.92 0.1904E+12 0.3153E+17 2006 348 1214 11.66 69.58 19.23 228.65 3.62 0.1621E+12 0.3287E+17 2006 348 1214 11.99 69.58 19.23 229.80 3.50 0.1517E+12 0.3019E+17 2006 348 1214 12.32 69.58 19.23 241.99 3.32 0.1368E+12 0.2656E+17 2006 348 1214 12.66 69.58 19.23 246.25 3.14 0.1221E+12 0.2978E+17 2006 348 1214 12.99 69.58 19.23 249.75 3.28 0.1337E+12 0.2276E+17 2006 348 1214 13.32 69.58 19.23 240.73 3.03 0.1141E+12 0.2552E+17 2006 348 1214 13.66 69.58 19.23 252.04 2.39 0.7084E+11 0.1681E+17 2006 348 1214 13.99 69.58 19.23 614.05 2.57 0.8195E+11 0.1817E+17 2006 348 1214 14.32 69.58 19.23 106.95 3.47 0.1493E+12 0.3649E+17 2006 348 1214 14.66 69.58 19.23 107.32 4.61 0.2633E+12 0.3089E+17 2006 348 1214 14.99 69.58 19.23 111.92 7.22 0.6460E+12 0.8006E+17 2006 348 1214 15.32 69.58 19.23 106.99 6.84 0.5795E+12 0.5918E+17 2006 348 1214 15.66 69.58 19.23 111.52 5.11 0.3242E+12 0.7050E+17 2006 348 1214 15.99 69.58 19.23 216.18 5.66 0.3979E+12 0.8650E+17 2006 348 1214 16.33 69.58 19.23 115.11 6.73 0.5613E+12 0.1164E+18 2006 348 1214 16.66 69.58 19.23 111.91 5.65 0.3959E+12 0.9971E+17 2006 348 1214 16.99 69.58 19.23 110.91 4.78 0.2838E+12 0.8799E+17 2006 348 1214 17.33 69.58 19.23 229.65 4.64 0.2665E+12 0.7807E+17 2006 348 1214 17.66 69.58 19.23 273.55 4.07 0.2054E+12 0.6673E+17 2006 348 1214 17.89 69.58 19.23 106.85 4.84 0.2906E+12 0.5591E+17 2006 348 1214 22.35 69.58 19.23 126.29 3.32 0.1367E+12 0.2627E+17 2006 348 1214 22.66 69.58 19.23 526.51 3.32 0.1368E+12 0.4217E+17 2006 348 1214 22.99 69.58 19.23 137.14 2.76 0.9439E+11 0.3024E+17 2006 348 1214 23.32 69.58 19.23 111.95 5.98 0.4436E+12 0.4382E+17 2006 348 1214 23.66 69.58 19.23 108.83 7.66 0.7278E+12 0.7309E+17 2006 349 1215 11.13 69.58 19.23 174.58 4.76 0.2810E+12 0.4967E+17 2006 349 1215 11.32 69.58 19.23 122.52 4.88 0.2954E+12 0.4682E+17 2006 349 1215 11.65 69.58 19.23 128.68 4.89 0.2960E+12 0.6009E+17 2006 349 1215 11.99 69.58 19.23 103.62 5.00 0.3103E+12 0.5622E+17 2006 349 1215 12.32 69.58 19.23 201.96 4.40 0.2402E+12 0.5742E+17 2006 349 1215 12.66 69.58 19.23 203.42 3.25 0.1313E+12 0.3499E+17 2006 349 1215 13.00 69.58 19.23 111.09 3.55 0.1563E+12 0.1980E+17 2006 349 1215 13.32 69.58 19.23 111.07 3.83 0.1822E+12 0.2649E+17 2006 349 1215 13.66 69.58 19.23 186.35 4.65 0.2676E+12 0.5316E+17 2006 349 1215 13.99 69.58 19.23 146.05 5.24 0.3406E+12 0.7059E+17 2006 349 1215 14.32 69.58 19.23 204.35 5.08 0.3204E+12 0.6868E+17 2006 349 1215 14.66 69.58 19.23 122.12 6.11 0.4636E+12 0.6458E+17 2006 349 1215 14.99 69.58 19.23 166.28 3.98 0.1965E+12 0.4263E+17 2006 349 1215 15.32 69.58 19.23 119.48 3.55 0.1564E+12 0.2948E+17 2006 349 1215 15.66 69.58 19.23 118.52 3.43 0.1457E+12 0.1903E+17 2006 349 1215 15.99 69.58 19.23 105.35 4.08 0.2066E+12 0.2644E+17 2006 349 1215 16.33 69.58 19.23 102.97 5.93 0.4358E+12 0.3513E+17 2006 349 1215 16.66 69.58 19.23 103.06 4.88 0.2948E+12 0.2716E+17 2006 349 1215 16.99 69.58 19.23 108.10 3.95 0.1935E+12 0.2137E+17 2006 349 1215 17.33 69.58 19.23 112.41 3.78 0.1776E+12 0.2131E+17 2006 349 1215 17.66 69.58 19.23 107.72 4.10 0.2082E+12 0.1801E+17
